Positive: Great use of color. I also love the layout of this site. The header is also very, very well done. The RSS feed is also very cool. BTW how do you do RSS feeds for color change? If you could PM that to me that would be awesome.
Negative: I think you should replace that google ad and make it match the site. Maybe try to drop it on the right side or something. Also get rid of that Syndicate thing under it or re-align that as well.
