I really like this design. I think its fairly well put together some of the edges and points where lines meet should be cleaned up a bitand there are some serious aliasing issues all around, but I still really enjoy the design and sharpness of the colors and fills as well as the forms displayed and can get past those previously mentioned issues.
What I can't get past is that big, fat, ugly-ass watermark over the whole thing. Putting your signature/web address on work is cool and great, but when done like this it really really really ruins a piece. Especially because its a graphic with limited colors and very simple. Fix that and this could be so much better.
