Navigation looks gorgeous, but your logotype is killing the header. Try putting a 2px. border around the downloads, maybe a denting pattern or something to make it pop in. Footer is pretty smooth, but I suggest adding colors to it (similar to katz, but light colors like gray and silver). Remove the stats and think of something unique to place their. Maybe something like "related downloads" to searches. Also, the search area should be more visible, try adding a light background to it and making the search button web 2.0.
