Looks cool but I prefer boxes with rounded corners rather than the straight edges. That is all I can see from a quick glance
Not really a big fan of traffic ninjas image.. Makes it seem childish in my opinion... Would also suggest removing the money background. All in all not bad for your first attempt and I wish you all the best.
I agree with desilator, the header image could use some improvement. Nice looking site, but it doesn't look quite as professional as some of the competitors. Also, I'm not a big fan of the yellow highlighting in the beginning...reminds me of that "buy this stupid ebook" joke page, lol (no offense). I recommended centering the text and changing the header image. Other than that it all looks pretty good. Nice job! Edit: Also, If this is your site where you are trying to promote your own products, then I would get rid of the adsense ads at the top, or at least move them to a more subtle area.
