The original is excellent. But I love the new Polaris stance, Marvel Girl's horn-rimmed glasses look, and Iceman's updated shininess.Excellent work!
Yeah, Polaris' stance in the new piece stood out to me. It's much more forceful and in control where she seemed more passive in Steranko's (awesome) cover. Although you could argue that a person so powerful yet seemingly not in control is even scarier. Anyway Mayhew took an already great piece, made a couple of changes (I also like how the X-Men can be seen better in his version), but otherwise made it his own.
Alex Ross...stand aside!
