well to me this hulk seems a bit odd but yes, after some reshaping I'm guessing he will look much better.
He needs a more defined six pack and his upper chest needs to be more muscular. Also noticed in most pics of hulk his upper chest tends to go up a little in the middle where to two pecks or w/e you wanna call them meet.
All that depends though on what version of the hulk you are working from. Also remember he has an extreme anger so to incorporate that in his body figure.
But yea..all your models are looking great! Especially Spider-Man!
