I did this a couple days ago, best bit I did. It's using an acrylic marker, just focused on form, rhythm and gesture.
May as well link my tumblr while I'm here: http://vulpespietates.tumblr.com/
1) You don't need your own thread
2) It's clumsy, you didn't even bother with the hands, and your "focusing" on rhythm and gesture failed and there's zero form anyway.
3) Don't put filters on your drawings you fucking dolt.
4) Don't fucking do the drawabox exercises in pencil jfc the dude reminds you every single lesson
