At around this time I had had so much fun with quick, loose hand movements on stuff I'd determined to be 'failures' that eventually I started out quick and loose with the brush pen, just letting lines get everywhere without trying to exert much fine control. I had some compliments from the other artists in the sessions these were done in on the style I was starting to develop but I'm not sure it was a style so much as a fun gimmick.
And in any case it's been long enough since I've done any life drawing by this point that I'm sure I'd have no idea how to do this again if I sat down and tried now. D:
