[EDIT: so I tried to fix AJ's butt after the many suggestions to do so.
I guess I should have waited a bit before posting this, seeing as it was a little bit rushed. I won't be tweaking this anymore as I'd like to move past this instead of sitting in one place.
Also if you'll allow me to be honest for a bit, I have to say being corrected by self-proclaimed "non-artists" is mostly depressing. Totally part of the learning process though, so it's cool.]
this was supposed to be a doodle, but somehow turned into something more.
