(Sorry for the massive fullview. My computer is being weird.)
I'm inking it right now and will post the update later!
Pose reffed from Posemaniacs, which I highly recommend to any person looking to better their human art. It's a free tool that has an archive of poses broken down to muscle, viewable on a grid in many angles, and it also has sections showing just certain parts of the body, like feet. I think you can even get it as a phone app. There's no fee but donations are encouraged. The person this trade is for actually recommended it to me a few years ago.
Background is going to be a bunch of fish and glow-bugs, things the character greatly enjoys. I will probably put it on scrapbook paper after that or another piece of paper so I can make the background like a roller rink a little, unsure!
Hoping to post a few character concepts later as well as updates on the image's progress.
