The whole thing seems a bit random...
- The background makes it look like it would be more of a grunge website but than you move to a clean feeling. Not to say they can't be mixed, but if you are going for that it's not portrayed too well.
- The computer in the header looks like your making a "design" type site. Reminds me of a Ps feather.
- The text at the bottom could use a light/white background. I never like using dark backgrounds with text unless it's just a header or an ad... I suggest using dark on light for content/paragraphs.
-The footer is a bit "off" of the bottom bar... One more thing - whats up with the Chinese mini tree!!
Ha... well touch up a few things and you should be good. These are suggestions, don't let them change what you think looks best.
Good luck
