Majavhv, your quick sketches, 30 secs and 1 min are still amazing. Great work on 'em.
I just wanna say, I really need you to draw more broader and wider strokes in these faces for 60 minutes of 29 second quick sketches of expressions???? (3600 seconds/29 sec=roughly 124 quick studies of facial expressions and features)
The reason why is because, your hands will be able to help you visualize those faces and expressions much better and quickly.
