Balina's head moof character has gone through a few interesting design changes as she's developed, and as a part of those changes, I was asked to try a wingit of her discovering her new features.
~ COMMISSION DETAILS ~
Media Used: PaintTool SAI
Time Taken: 1 hour 30 minutes
Commission Type: Wingit
Completed on: December 29th, 2015
They're the connection ports for her extra arms. You can just barely see the sides of the other set under her armpit, as well. She doesn't typically sleep with them installed, and not having to draw them saved precious time for the speedpaint.

Still the best single reference of 'em. :D
