Here, guys. Have a base.
Some of the poses have lines through the arms, this is to show where the body is underneath to make it a little easier to edit.
So, yeah, feel free to edit the hell out of it. Just remember to credit and link back.
EDIT: I added 9 new poses, some color palettes/expressions, and 5 slimmed down poses. I also went back and edited some of the existing poses.
