Hey that’s impressive… a lot less messier and your lines are showing a lot more dynamic energy…
The technique I was talking about takes is a bit timetaking at first, but the more you do it, the faster you get at it and after a while you will notice you are drawing a lot more accurately…
we even sometimes do exercises… drawing someting without looking at our paper… ofcourse very funny results but actually I really dig the why for this kind of exercise… it forces to focus on the directions of the lines… every line we draw has a certain direction… in a portrait or figure drawing, the direction of each of these lines can be quite decisive, setting mood, energy… telling a story
I think your overall feel for proportion is really good… would love to see you take one of the gestures you really like and develop it further…
REBECCA KIMMEL’S Anatomy Review 002: OPPOSING CURVES could help building a full figure from a gesture drawing I think
If you would like to shade as well I would suggest taking a look at following threads (also by Rebecca):
TUTORIAL - General Principles of Anatomical and Figurative Art / Cross Hatching
