It was rejected because it's copy and paste of doodads. But who gives a fuck? I think some exceptions should be made for things that look as awesome as this.
As for giving credit to blizzard for the texture, well, this skin is made for blizzard's game, which makes it kinda obvious. It would be retarded to credit blizzard for things in their own game seeing as if we did we would be crediting them all over the place. It would be different if this was being used for another game.
I hate hardcore artfags that don't realize that with things like this, it's about what looks good and not what takes time and effort.
