This is a character I designed about a week ago. I had drawn some sketches of her and posted some of those on tumblr.
She's a very sweet and vocal person who takes up boxing as an exercise and hobby. Her arms are very stocky from socking punching bags all day, and she's very "top heavy". In contrast, her hips and legs are quite thin and spindly, as she doesn't really use them all that much when she exercises.
I've got some other ideas for characters that exist in her universe, so I may work on those when I have the time.
Hope you enjoy!
