Spider-Man Black Cat - The Chase - WIP

Working on another pinup, this is a fun one, at least for BC it is lol, usually BC is the one who's chasing after Spidey.
BC hair and back arm are gonna be tricky to pull off, i dont want to totally obscure her arm because it'll look like she only has oen arm, but her hair whipping back and angle almost dictate that it should be covered up.  Maybe if i dont have it flair upwards as much and have it going almost straight back towards her butt, or flair even more up in the air...hmm....
