Here's one that I owe my client in a few days. Any suggestions? KeyShot 2, Photoshop -

Nice porsche model!
Truly impressive. Good work with all the subtle lighting from within the house. Have you tried adjusting the gamma and brightness settings? I think a little more contrast would help.
In the end I took the color out because I wanted more realism. Cheating, I know, I do it often. Also a shot off the back of the house -

Try setting all your materials to a diffuse white color and render out the scene again. Use this new rendered image as an ambient occlusion pass. Set the AO(ambientOcclusion) pass as a layer above this image in PS and change the mode to multiply. The AO pass is used for shadows and you may have tweak the shader to a slight gray or in PS use curve/levels to add more contrast and bring out more tone. I also like to add some grain, DOF or chromatic abbreviation to help sell the image as being "real".
May I say that you scene is a brilliant one!
Here are updates to both views. The previous versions were meant to simulate lighting at dusk, but I abandoned that. Here you see mid-day shadows that show more depth.

These are really good. I am impressed.
