Thanks so much for the feedback everyone! I think I'm gonna do something between A and B, because while I like C aesthetically a lot-- it does give this retro feel, but also a lot more of a like... "Proffessional" hero one, with the gadgets and ear pieces and stuff. (She makes me think of Jem and the Holograms, tbh. Maybe this design can show up later, LOL) Another tiny issue with B is that it does look super amatuerish, and this person is a professional internet celebrity, so it needs to look a little more official? Since the gimmick is being a vlogging superhero, she'd probably work to look the part while not having any like actually useful tools on her, besides like. A pocket, or something.
A is definitely going to be the main inspiration for the design, I think, though!! Thanks so much! (Also, I just noticed, A has like... JoJo Siwa hair. I didn't intend this, but here we are)
