First of all, wow. That's a lot of windows with "Ch" in it. Not as much as when I proxy bombard this site, but it's still a lot. Secondly, I like the black and green feel of it, those colors really intertwine themselves well, especially in a mechanical environment. You're doing a fine job Blizzard.
The banner, it would look better if there's a little more brightness with the center spot in the middle. In fact, with the whole center spot vortex-esque whatever, there can possibly be a better effect for it. There's a good background though around it, I like that. The text effects are nice, but my least favorite area would be the "P" place...Probably because it's directly over the center of that...You really did a nice job, once more Blizzard.
