I agree pretty much with all of the above. Fear of the Dark Eddie and Shaman Eddie are awesome and I definitely hope to see them in future updates. As far as 7th son Eddie goes, just the torso like Speed of Light Eddie would be good, and they DEFINITELY should lose the IM t-shirt. For Cloud/Brave New World Eddie, the Wallpaper is just fine, but if they really want to go with a concept, it could be cool to have some kind of abstract form of Eddie, ACTUALLY just a cloud with some faint Eddie features...

Anyhow, like Flann said, album covers should be canon.
