So the same friend who recommended that I try drawing directly in pen also recommended drawing my subject upside-down so I can focus on shapes and not on what I think I see. This was a bit of a rushed job. I definitely messed up that one hand, and the shapes in general could be more accurate. I'll probably have Bunny do this same pose again some time so I can try to do a better job. Bunny is patient.
