That bg does not go very well. The perspective is off, the horizon line is too low and there is not much sunlight in it.
Maybe go with something along the lines of this at least perspective and lighting wise.

glad to know u are still watching my WIP
thx for comment
to pap87
yes i agree, still don’t know how to make the perspective of the HDRI to match the camera in 3d application
may be drop the HDRI .
any good background resource like the one u post?
I think C is the best… The others look more like a cabin in the wood background. Base on the type of windows frame, I will story your picture to be a home interior, so to need a outdoor more rural less river or lake.
I think A is the best.
The others don’t work with your lighting. A seems to have the exact same light direction shown on your windows. I won’t pick something with close up water since someone would expect relfections on the water of the house she sits in.
The others have different lighting so you would expect having shadows on the ground from the house and not light coming in from the direction it is now coming into the room.
add 2 , most of the people prefer rural,
forget to mention the BG is composite on PS, there is white color shift come from window.
i like the flower on g. but i still add f even it is a lake because a little away from the lake.
waiting for zokana comments ~ hope he will be back soon
I personally prefer ‘f’ as I really like the picturesque range of colours in the scene, the other thing is ‘g’ at the moment the background angle is too close to the ground.
I think a combination of ‘f’ for the far background, & ‘G’ for the foreground would be best.
Anyway, no matter which background is chosen, the perspective & scale need to be worked on to integrate the 3D models. At the moment, they looked off.
None of your backgrounds are going to work because, as pap87 mentioned, the horizon in all of the photos are too low. From what I estimate, the horizon line in your 3d render is above her head, by almost a full head length. If you want the horizon within the scene while maintaining the same camera angle, you will have to change its focal length for a wider field of view than you have now. If the horizon line were in the scene (say at the level between her eyes and head top) that horizontal grill bar (passing the top of her ears) would appear horizontal, not angling up so much, as in the current 3d scene. The horizon line also looks to be tilted down/left.
So, if youre going to use the camera at its current FOV, youll have to fing background scenes where the hoizon is up and out of the picture.
Example shows where your horizon line is compared to the photo ref.
Oh perfect, kind folks here - youve got a lot of great comments! And then Quadart just said it all.(i also totally agree with him about the horizon-wide angle relationship, but a wide angle might kill your babe, giving her very long legs and a small head) and yes, my PO was off concerning perspective, so its perhaps also a bit my mistake.(i dont agree much with the vanishing point though shown by Quadart, it should be further up, regarding the high position of the camera, also with a wide angle lens)As i see it.
As for the mood: I like some of the proposed BGs, except those which look like a postcard or a kitschy wallpaper. Personally i love e for the colour mood with all that pastel colours, which perfectly underline the skin instead of celebrating harsh blue (but wrong perspective, strong distortion, almost like taken with a fish eye lens, and the impression of being on a house boat).
I could also see some Japanese garden thing as BG, if going for romance. But not too postcard like, and as Quadart mentioned: taken from above (not just head level).
edit: forget the idea with the Japanese garden (didnt think it fully over before) >> you would need traditional Japanese windows then…
thank you for all comments again
especially the carefully explanation about perspective from Quadart and papa
finally u back zokana
actually what i am worrying about change the camera FOV is like zokana mentioned that may destroyed the photo
i am thinking lower the camera position first
but not easy to find a correct perspective photo
i will try it out myself
like what u did by drawing some line on the photo
now i am taking care about the satin material
about the window
i think zokan mean some normal window
if u ask about tradition japan window
actually is like this , the white part actually is paper. . some specially made paper . u can use a finger to make a hole on them when u see some movies
ianlai–I wasnt suggesting to change the FOV significantly, just saying if you were to keep the camera angle you have and bring the horizon into the scene, you would need to change the FOV (and slide in closer), which as we know would introduce unwanted distortion. I think you can tweak the camera angle to match the ref photo of the actual woman sitting on the bay window sill. The ref doesnt look much different then your image (minus the post counter clockwise turn of the image) and seems to be what youre after. You may have to change the FOV a little bit wider. The FOV of the ref appears to be wider than what youre using, with the camera lower, pulling the horizon into the scene. Your background image horizon has to match your 3d scene h line.
What is the focal length and aperture width of your scene camera?
Nothing against slight changes of the focal length. Ive meant more that trying to get that same extreme wide angle feel of the BGs wouldnt work (those BGs shown have mostly a very strong distortion toward the edges). Ianlai could try perhaps to get a slightly more wide angle, when having a BG, but he should find first a compatible one: no Alaska, no Swiss Alps, and no Japanese garden à la Kill Bill (but it may have nonetheless some relation to Japan). The BG really doesnt need to be an outstanding photograph, it only needs to match the scenery.
thank you very much
i am entirely noob about the camera , like perspective , camera distortation
the camera atm is 85mm lens = 23 .9 degree FOV
I suggest you make a horizontal plane with tiles or checked pattern, each tile or checker a specific length, say 1 metre, then find stock photo that you wanted, then make imaginary floor tiles appropiately 1 meter per tile, & see if he can match somewhat.
But I suggest you can also try to get your camera & took your own background, then you have absolute control of the perspective & angle. I am sure you can find a nice place in Hong Kong that can be used as background.
change the white satin
white satin is quite strange that it need more treatment than some darker color
finally find a fix on it .
50mm 39.59 fov 36mm aperture width
not many BG is found because the requirement is quite specific, high angle
camera,large resolution , right scale , right mood
i try to find some with grass , flower. but actually it return some close zoom of the flower or beautiful scenery but with wide angle as the old bg i found
i use c again (source from papa), the perspective is quite good
feel free to provide me some good photo or keyword for me to search myself
or lower the camera more?
thank you again for everyone comments
‘I’ looks best, but the flowers need to be scale down. They look huge from the picture. You need also to make the glasses in the frame, as it looks like there is no glasses (only frames).
Have you consider also maybe make your own background. You can get some free stock trees from the net, & software like Maya came with some basic plantation & flowers & they will look passable if you add some dof blurring & over exposure.
Also, she have granny left foot. Maybe tune down the wrinkle, roughness of the foot.
