I think the main thing I dislike about the site are the borders/gloss/3D look on those thumbnails. I prefer some clean and simple, but hey, it's not my site ;p

The 'Home' 'About' 'contact' text seem quite weak, looks pixelated and the Nikon camera has some white edges around it which could be removed >:

Have you not uploaded the mono images? I get a 404 message when trying to view them

The mono image is pretty hard on the eyes and is hard to actually know what the text say.

But besides those points, some really nice images on there, great colours on that cornflower
