In terms of pose I think what you have is nice, the proportions seem well as far as I can tell. I think what can be improved is the dynamism. If the character is moving at a high speed as I believe is implied, then any long, loose article of clothing or accessory should be flowing in the opposite direction of where the character is moving. In your case, that mainly applies to the loose part of the trench coat - if Spiderman is falling, that part of the coat should be flowing upward; if moving to the right, then it should flow to the left, etc. The other thing I would add would be action lines in the direction he's moving in. Both these changes would help communicate how and where's he's moving, as well as make the piece more dynamic. I hope that helps! | Artwod Feedback
