This thread will be locked on January 5, 2009. (I know I've been saying "at the end of the year", but I want to give it a few more days and make the closure line-up with when we'll be starting the next challenge...)

PakosM - Looks good. It seems that there's a large amount of gray in the scene, with gray patches on most of the fruit. Maybe try a little more color and reflectivity in the fruit, and give your key light a warmer color to contrast with the cool fill color?

phil-w8 - The moon light is fine. Think of that as the key, and the soft illumination from the sky as the fill. You just need to add the fill light through the window, not take away the key.

gashworm - Nice job! If I were trying to add interest to the scene, I'd make it more clear that the light from the hanging lamp was hitting the walls, with a shadow of the lampshade visible at about the height of the lamp. A little specularity could help break-up some of the surfaces, too.

sumitchanda2009 - Welcome! If you're having trouble getting an image to display, try posting it to a photo sharing site such as http://imageshack.us/ and adding a link to the .jpg file with the insert image function. Once you have a more established account on cgtalk, with more than 4 posts, you'll also be able to attach images directly to your post, although that results in just a little thumbnail, not a full in-line image the way an image link does.

Hi Jeremy, thank you for this opportunity. It's pity you are closing this thread. Here are some of my tries. It's very interesting to hear your critics. I'm sorry for posting it alltogether, but well there's no much time left.

mister3d -

Nice work on the fruit scenes. I think the curtains in your kitchen scenes could use more translucency, so they really look like back-lit fabric. Underwater looks good. Really when you're underwater and look up at the water surface, the surface is mostly reflective: You can only see-through to above the water in a tiny area called Snell's Window.

Good work on the eyes overall. That edge between the eye and the eyelid is tricky. There's a black edge now that looks like a refraction problem, try to get that transition to look organic and wet. Between the eyeball and the tear duct in the corner there shouldn't be any line at all, it's just a soft transition there. Eyelids and eyelashes also should block parts of the reflections near the upper lid.

The candle scene is a good start but could use another version: the shadows don't all seem to be coming from the flame, especially the rectangle above the picture frame. The wall on the right looks too bright to me, especially lower down near the edge of the table. The front of the table also looks a little too bright, especially on the right where it's brighter on the front than on the top. The reflection of the plate with the incense looks brighter than the bottom of the plate itself, making that area too bright. The candle wax might be a little less reflective as well.

Great constructive feedback Jeremy, thank you! I agree on everything. I knew something wrong with my water scene, I guess I will need to read the dedicated thread to improve the water look. The same with candles scene, this shadow looks unmotivated. And eyelids perhaps need occlusion pass.

Hello, here is my try at the fruit bowl. I just noticed this thread is going away? Hopefully I got this in in time!

Leotril, nice work. I hope Jeremy doesn't mind other's comments. I think your borderstones have too heavy bump for water streaks, and maybe the asphalt could be a bit darker and you could make some variation, like pools of water or cracks, especially considering you made water streaks on the borderstones. I like the rest, those soft gradations of lighting on different planes, and textures are good. And nice work on chrome. Did you use any fakes with lighting or it's all quite motivated and no cheats were used?

Hi Jeremy. I appreciated you comments and made another pass at the fruit challenge hoping for some improvements based on your thoughts. I would have redone them all, but moved on to complete the museum challenge.

Thanks.

earwax - Welcome! That's a pretty good start on the fruit bowl. I think the light is too frontal (like a camera flash) and you'd get better definition if you moved it to the side more. It seems as if you could use some fill or bounce light, just to fix the parts of the fruit that are going black. I hope you'll try the new challenge that starts on Friday.

Leotril - Still good. Still need more illumination from the flourescent tubes into their own lampshades. You need illumination from the headlights on the street in front of the truck, really that area of the street is already bright enough, you just need to give it the shape of the headlight throw. I agree with mister3d that the grooves on the curb are a bit deep. It seems as if the curb on the left side is missing, too? I hope you'll try the new challenge that starts on Friday.

dcbeatty - The first fruit bowl is pretty good, it just needs some fill or bounce light, to fix the parts of the fruit that are going black. In the second one, the window reflection is not very realistic, maybe you could position the window at the same place that your brightest lights and highlights are coming from, so it would be in the middle of the highlights? The bounce light seems too bright on the banana, but there is no bounce light on the apple or under the apple leaf. I hope you'll try the new challenge that starts on Friday.

Wow, over 1000 posts in this thread! Congratulations to everyone who posted work here. As planned, I am closing this thread now. A new challenge starts at the end of this week, I hope you can try that. Later on, we will also have focused flashback threads that use some of the old challenge scenes as well. With focused flashbacks, I hope more of the community spirit that exists in the launch of new challenges will also be brought to an older challenge scene. See you in other threads!
