Upside Down Shapes of the Semi-Nude Figure Drawing

Done as part of a 6 hour class. My current goal is: Learn how to make my funniest drawings the most alive and motivated from within. Here is my latest figure drawing in about 2 months. My pose looks or seems funnier in it's presentation to me. What do you totally think? What can I do to punch this up or am I all set?? Good night.
