So it's been a while since I posted anything, but that's not because I haven't been busy.
I lost track of how many hours I've spent on this, but it's a lot. (I may come back to it and make minor edits. If I make a lot of edits, I'll include a new version at a later time when I post something else.)
edit 1: I've tweaked the legs, especially the knees, and added some lines to the pants to help show the shape and angle of the calves. I'm still not 100% on it, but I think it helps a little. (I've kept the old version in the post in case people prefer that one.)
There is an extensive personal canon as to what is going on here, but I'm going to let the viewer decide for themselves.
