Anything else... : I think the colors you use don´t mix properly. For example you have in the first layout two different greens that should not be used so close to each other. Then the menu green and the orange are very saturated but you use desaturated and gray images in between them.

Yup. Initially proposed the standard corporate green but the client opted for a variation of it as they felt it was too much.
The main piece with the gray images is actually a flash piece, sort of like a kwiks banner. The images will be colored when a user mouseover them.
