Nice designing for WOW.
But you may change these........
1) make hover image effects for all image link buttons. (when mouse over black & white image)
2) Contact page: Form fields may put in each line (may be change some another font like tahoma, verdana?)
as a undercontructed website can't describe other parts. Niza diseño, la buena idea, pero se puede mejorar más
The only thing that i can see on a graphic view is the smoothing for the logo font but that only be like a problem if your going to enter your site to be like reviewed by a graphic site and they look closely at the font for the logo and make a score partly based off that.
