Hey janick-
the thing that my eye has an issue with is the lighting. If you look at the back ground image you used you will see there is a lot more contrast between the light and shadow. A typical sunny day casts great amounts of light into a scene, which accounts for why you get the contrast.
Looking at your 3d model, you'll see that it doesn't have the same contrast. In order to achieve this, you will have to increase the multiplier of your main light source, and also darken your shadows. You may want to slightly tint your shadow colour to a blue or green; whichever looks better when rendered.
I also noticed on the bag of coffee, there appears to be a kick light in there casting light on the right hand side of the bag. Realistically this wouldn't happen unless there was something there reflecting light on it. So for this scene you may want to get rid of that light.
The highlight on the coffee cup should be on the left side of the rim as opposed to in the center.
So basically look at your background image, figure out what direction the sun or light is coming from, what colour that light is, what colour your shadows are, and then apply that to your 3d scene and hopefully this will help. :)

Made a few changes but I am still not quite satisfied, IŽll try to make the CG stuff a bit brighter tomorrow. Although I must say that the outcome of the second pic. is much better in my mind !!
But I would still be very happy to get some comments, they are helping my down the path !!!
:p
Hi!
What i think u would benefit from is rendering using a hdri file.
This is basically an image which carries the light source of the backgroundphoto, wich afterwards will be rendered using radiosity. I dont know how to achieve this in 3dsmax, but id definitely look for some max hdri tuts if u have the chance :)
