I spent several hours working on it, and I still think it's weird. The original sketch was one of those that sat in my sketchbook for a long time. At least three years, maybe four. I drew the figure first, and then built her something to be sitting on, which is probably part of why it feels weird to me. It's like trying to do all the shading on a figure before I've done any of the lines. Yeah, you could do it that way, but it probably wouldn't turn out very nice. (But you should really try it some time. It's a good exercise. Did I mention that 'exercise' is artist jargon for 'painful stupid back-assward way of going about something you already know how to do, but it's for your own good'?)
Unfortunately for my brain, this lady wanted to be sitting on stonework. (Actually, it was either that or hyper-future architecture. However hyper-future would require transparency, and I really, really didn't want to go back and try to draw her legs at this late date. ) Stonework is awesome and all, but it requires thinking in more exacting 3D than I'm used to. I tried to do proper two point perspective, but as I've found in the past exact perspective looks forced and staid. So, I just sort of eyeballed it.
Besides, you were looking at the lady anyway.
