Yeah, Nightcrawler's got the tattoo thing going on....
I didn't recognize Rogue at first.  They don't really have her hair lit up, so I didn't recognize it.
I think that's really one use of individual costumes:  trademarks.  No matter how the artist draws the character, if the trademark is recognizable, we'll know that's supposed to be the Beast, or Spider-Man (c'mon, how much does Toby Maguire look like Peter Parker?), or whomever.
BTW, ol' Kurt doesn't look too happy.  Is he an X-Man, or a foe in this movie?
That's what I liked about the X-Man movie:  None of the bad guys died.  The Batman flicks kill them off left and right, and of course the Green Goblin died (or did he?  He was buried, that's all I know), but Magneto, Sabretooth, Toad, and Mystique all survived.
If they're dead, I want to see the bodies.
