Amazing, would buy this frame in a heartbeat. I'd lose the tail idea though in the top right illustration. The Bottom left illustration is the best aesthetically looking, very beautiful job you've done there.
The waving hair would be so cool but might be a challenge for the design team, though if they did implement it, it might set a precedent and pave the way for more frames with flowing hair and other creative ideas.
You should definitely put this on Steam Workshop to gain traction and let people vote >
