I was working on a new sheet of Aftyn nude figure drawings, and got a little hung up on the unfamiliar proportions on this particular booty pose. I was having a hard time getting it to look right, and having to also imagine what was happening beneath her shirt was just making it worse. So instead I drew it as presented in the reference, which you can see on the left, and then made a copy to put my imagined nude pass on it. I’m pretty happy with both, despite the imagined pose depriving me of the “yes, that’s right” sense I can get from matching the reference.
