I tried again. This time I'm fairly confident in this from an anatomical standpoint because the pose wasn't particularly difficult but there are other things I'm less confident about.

>The hands. I have never been good at drawing hands and I doubt that the man's hands in this case look correct or pleasing. What do I need to focus on in order to draw them better?
>There were certain points, particularly with the tracksuit top, where I felt I got arbitrary with the shading. This is a recurring theme where I'm not quite sure how light hits clothes or how they fold naturally. I tried minimizing folding but I could certainly use feedback on how things were shaded
>Less priority here, but how does that breast look? I haven't really drawn them from the rear before so I'm not sure if it looks too flat.
