Spider-man look pretty cool but like Haseyo said the old web ball was better. I mean, it doesn't even look like it come out of his wrists and when at close range it miss the target every time cause the web ball appears 3 feet in front of Spidey.
Speaking of the web, in his victory taunt was it impossible to use Sheik's whip like in his entry instead ? It would look more like a web in my opinion. the current one sort of look like a web line but Spider-Man doesn't seem to have much grip into it (it look kind of beside his hands rather than in his hands) also even the little web ball thing desn't seems to be attach with one another.
While on the topic, can the whip be animated ? it would have been nice if spidey could use it for one of his throw like the one in mvc (although yours are pretty amazing

). Another reason why it would have been nice is for his side-b. This is pureely animation wise but I think it would be cool , if the web would look a little more "loose" when you shoot it (similar to Olimar's Pikmin rope or ZSS laser whip) and when Spidey pull his self forward it become straight and hard looking as it look right now (not sure if it's clear). Being able to grab to ledge with it would be quite nice too. i mean since sheik could do it clearly spider-man should be able to do it. Still, this pretty awesome PSA and animations you done here ... as usual.
Of course these are just suggestions, but if they're possibles, i would highly recommanded you to do them eventualy no rush.
Also, just out of curiosity, what will be you next project ?
