I really like the Blood Elf and Draenei themes! As far as inspiration goes for other skins, could you possibly throw one together for each race? Just along the same concept as the other two, racial symbol on one side, picture of said race on the other, with unique color schemes and borders? I happen to play a blood elf, orc, and tauren and would simply love to have a racial skin for each one.
[Edit] I'd try to throw a few together myself but the file extension are completely foreign to me. The Photoshop/Gimp work isn't the problem, it's the file extensions, and the fact that Photoshop is currently not speaking with Vista. Okay..Photoshop is also a problem. lol.
