Overall it's good
I personally think it's better to have the site as a whole aligned in the center of the screen. (Not the text, just the actual site.) It is pretty condensed and has small text.
You do a good job of creating the whole icon feeling with the site and you jump right into it so there is no mistaking what the site is about. That's great!
If I was going to change anything it would be centering the site in the window and making the text a little larger so it's easier read. Also, finding a nice way to unclutter everything a bit. You can usually accomplish this by creating a better categorizing system so you can get less on each page without hiding the items.
Hope this makes sense, it's late.
