pretty good. But its weird that "get your ad here" is more brighter and better looking than your header section. Try to increase your header section height.
I like the background it pop out the body design... by the nice design bro... Try adding some graffiti paintings on your background and see if will add up some skater punk touch
speaking from a design point, your over use of a simple gradient is poor, no offense just being honest.
Well... I've seen your main page and it looks awesome. I would (apart of design, which is awesome) put more content in general. I think you may get more customers.
