Posting this as sort of a follow-up to a discussion had in the comments a bit ago. All apologies for the terrible phone photos; levels adjustment couldn't save them without washing out all the information, but you can kind of see how I build up figures when drawing from this. Not pictured: my final pencils, and countless sketches of similar poses over the years. Notice I had to change a much more dynamic, natural leg position later on to make a bit more space.
