yea, the quality is kinda iffy, would be nice to see if you can make it look beautiful in a mainstream kind of way.
although the positioning of the box's kinda annoy me, and the diagonal bars do as well...
keep playing with it to make it amazing.
P.S. it took me many designs to land with one that stood out from the rest. overdoing it in photoshop isn't always the best way to go. I like to keep it minimalistic but very pleasing to the eyes. Also note that it took me a while tinkering w/ the overall layout for the links and css styles to land with one that i loved
ex:
My Site btw, that is design version 5.2~5.3. the main links were originally on the left hand side with a dark gradient iirc similar to shape of the rest, but that idea was shortly scrapped as I grew away from sidebar links in favor of links on the top of the page.
