sketchy sketch (Patreon)

I've been messing around this pic in between Kat project pics. I'm pretty sure some of you are familiar with the girl in the middle, my friend's character KR-1.

She came up with other OCs recently so I sketched them together. I'm not entirely sure if I should finish this one but I just want to share the progress here c:

What do you guys think? Should I finish it?
