Trying this again on a whim.

I think I finally figured out how to draw a knee; never could get it to come out bent before, even though it looks wrong with the rest of the sprite. I just could never get it using a single line. Really just trying things out as I scribbled with the pencil and this happened. I dunno...I just can't get it to bend properly and look natural, same with the elbows I feel I've made a bit of progress though.
