Looks like a cool site, all though.. This is one of the most terrifying things iv seen in a long time
think its a clean, neat design. Particularly like your header graphics, feel it is very suitable and appropriate for your theme. - u may want to put the sizes on the main page instead of having to click on individual items to see it. I know i wld find that a big bother since i will prob be looking for specific sizes of art - some arty farty names might also go well for each piece instead of a code. creates more sophistication to the products. - shd include impt info like shipping policies, guarantees, packing, etc. - what are those pieces under the main category pictures supposed to be? they don't seem to be in any category. just some suggestions =)
Nice and clean, but add a background picture to your sidebars. They look more like adsense ads than anythign else (maybe its just me).
