First thing that pops out is that Spidey's legs are a little short. Legs are usually as long as the torso. Might also want to give him a pose that suits him more. I can't remember what issue it was, Spidey was talking to a girl and she asked him: "why are you always hanging off walls and crouching?" and he said something like "I feel weird just standing around dressed up like this". Haha, I'm sure I'm remembering that wrong.
Oh, yeah....also might not want to cut off DD's feet. Not sure who's rule it is but I've heard it's a no-no.
Anyway, let's see some more progress!!! Are you going to ink and color? I say push it as far as you can
