The problem with these pictures, with the exception of Jean and maybe Angel, is that although they are artistic, they miss the mark . . . that is, they fail to convey the character of the X-Men (rather than simply the character of the actors).
For instance, this picture illustrates the attitude that is Wolverine
This does not
While the latter one may be more colorful, and Wolverine may be overly dramatically posed (on a barrel?!), something is off, although I can't quite pinpoint it . . . I'm just not buying into these . . . oh well, who's to say come May?
On a side note: I don't know how anyone can complain about X2's promo. pics. being airbrushed, as these have clearly been airbrushed and photoshopped to Hell and back.
