Second in the 'Swimmers Series'

What could I call these drawings? 'The Swimmers Series' sound like a reasonable title at this time. Until I can fully pinpoint what these are about it will have to do. Here is the second in the series.

Pigmented black pen on school paper. I'm playing with the margins and the placement of the image on the paper. I hope to make three at this size and then it might be time for a large one.
