Digsy Doodles IV

I started another project that I won't finish! This time it's to draw every X-Man in the order they joined in my favorite costume of theirs. Here are the first three.

PROFESSOR X
(Jim Lee's 1991 design)

JEAN GREY as MARVEL GIRL
(Don Heck's 1967 design)

CYCLOPS
(John Cassaday's 2006 design)
