The butterfly isn't bad or good where it's at. It looks a little odd to my eyes because it's facing the same was as his head, but then again, I don't know anything.
The only thing I don't like, is it looks like his arms are monkey arms, they look completely darker than his other skin and looks like he's covered in weird body hair. Body hair is one thing, but I'm not sure if he's just really hairy or if the editing is making him look extremely hairy.
Other than that, it looks fine to me. But I probably wouldn't buy the CD just from seeing that cover.
