Vivian James? What is familiar to me is the Paul Robertson -ish style

(the modular weapon also helps)
I'm not too sure of the black outlines (personal preference-- I know they're integral to the style), especially when the black 'pools', creating clusters instead of 1px lines.
To animate the hair, I think you should first off have a static version, and
then work from there.
Maybe the hair should just bob backwards at the bottom, a little? I also am not experienced with animating hair

Nice work on the feet animation
Edit:Literally just found out where the character is from, since this came up on my feed
