The artwork came from a thread on ConceptArt.org where the artist, Marko Djurdjevic, posted a ton of artwork from his time at Marvel. The artwork is beautiful and there are some really attractive pics of Daredevil, Hulk, Spider-Man, and characters from Thunderbolts.
I don't know what the artwork of this character is for (oneshot? miniseries?) but I can't wait to find out.
