Hehe - the background looks stupid in the main menu, doesn't it?
The idea is really good and the music screen looks awesome. But I would rethink the menu and its background. Good work!
This one looks wickedly sick, thanks dude!
I only wish they can have a separate background for menu and music... lol
When you actually run out of ideas to make skins (which I hope you never do) give us a shout :D
