- As kyro said, it's a bit too wide.

- The logo could stand to be a bit crisper. Maybe take a look at some of the techniques from http://psd.tutsplus.com/designing-tutorials/elements-of-grea...

- I'm kinda stupid, but I didn't realize the scroll bars were scroll bars until I saw someone else's comment. Also frustrating that they seem to work with mousewheel only.

- As azrealus said, it looks strange while you're loading up. I'd hide everything until it's all loaded and show it at once.

Good start, keep it up.
