First up, its way to wide. It doesnt fit on the screen im currently using.

The whole thing seems a bit flat : -/
Like, no textures, no gloss or grunge. Im not sure what this style is xP

I see both grunge and gloss. Clearly a Web 2.0 site. Main problem with it is, as tov said (he is a good critiquer) its too wide. Also why is it a square the ends abruptly then goes to a light colour?

Another thing is say is put some slight gloss on the nav bar etc.

Decent effort tho, maybe dont use kuler next time cause those kulers disgust me.

I wouldnt call the background grunge, and the only gloss i see is on the title.
Using gloss and grunge together is hard to pull off, and im yet to see someone do it, though i havent been looking.
I say, stick to one.
Either way, you dont have enough gloss/grunge, depending on what you want.

With the colour scheme you have chosen, i suggest going with grunge.
