Just a few suggestions, as far as colors / concepts are concerned. Your site is Casa Verde, but the main layout is gray + blue. Why Casa Verde? I would imagine that GREEN would be a more prominent color in that case.
Also, you have Blue, Green, Red, and Orange all on the same navigation. I think it's kind of a neat idea to have different colors for each section, so it adds to some sub-conscious organization... but they should all fall into some sort of color scheme. The colors you have there are all really strong, and conflict heavily with one another. Take a look at this color wheel and you may get some ideas.

Also, there is a bar above the navigation with seemingly no purpose. Why is it there?
I think you've got a good start, I'm just trying to stir up some more ideas.
Good luck.
