The site is clean and tidy, expansive and works well but here's a couple of things from a passing glance.
The facebook like counter on the lightbox is being cut off.
The Pricing menu item is being wrapped to the next level down on my machine running firefox.
The design is a bit, I dunno, it screams more software than it does photographer. The images should take pride of place and the whole thing needs a bit more design work to finish it off.
