His first few issues of New Mutants are actually quite nice, and I can understand why I thought, in those early days, that he was a new, young artist with great potential, and an original and interesting style. I can still see that.
But, very quickly, his artwork became a lot more basic, increasingly disproportioned, and reliant on blatant swipes, from the middle-to-end of that run. You might suspect that this short cutting and sloppiness was due to deadline pressures, but it would be stressful to go from unknown status to rising star, more or less overnight at his age.
