On the left is a piece of art by the late Michael Turner, who passed away in June of this year. On the right is a submission in the Blizzard Fan Art Program, by Emiko Setsuna (or Dênakê). Tipster Ron pointed this out to us, figuring it was worth a mention. If you notice the two pictures look very similar, you're right. If you're not convinced, look very closely at the ladies' left hand, and how the fingers and thumb are placed.
I'm not ready to scream "plagiarism" here (or Laaaaaaaand!, if you're familiar with comics). The idea of "inspired art" and "homage" is very common, and there are only so many ways you can pose the humanoid body. The Blizzard Fan Art Program doesn't have a commentary feature, so it's possible Setsuna intended on crediting Michael Turner for the inspiration. If you consider the timing, especially, it's likely Setsuna was memorializing Turner, as he only passed away a few months ago.
Still, it does make me wish that the Fan Art section did have more information from the creator, so we could draw a conclusion more easily.
