Yeah the first thing I noticed is there wasnt a flash navigation functionality so I had to keep going back to the category's on the left and then wait for the header to slide in before I could check out the desktop section for example after being in the sig section of artwork. You might also want to have the category words part of the links as well instead of just the gems at the left. Took me a second to figure out where to click to move around. I'll give it another look later on but I need to get through the rest of these posts. First time I've had over a page of new posts here. Very cool.
