The next what...

A while back I had injured my knee playing ice hockey.  I'm almost at the stage to a full recovery:  Physio.

 One suggestion I got from my mom, who happens to be a nurse, is to go to a swimming pool and strengthen the muscles of my knee and do some kicking exercising underwater.  I guess that idea locked itself onto my subconscious.  Because, while taking a nap later in the day, I dreamt up something crazy.  And, this early drawing of the next painting depicts an image from that particular dream.
