Slightly leaning figure, charcoal drawing

I think I got shoulder girdle better in here, but there's still room to learn. This pose took 20 minutes, but I feel like this isn't the easiest pose to draw in general. There's a subtle lean on the stool, and it's hard to catch it for me.

Two Standing Figures, charcoal drawing

I've been studying Bridgman's book today, and I realized how static my figures are. However, I must add, that's the way models present the pose... I need to exaggerate turns and twists more!
