Well, well, Sonnemaker, I must admire your 30 second-1 minute quick sketches, cause they're on the right track in terms of action and acting.
In the meantime, my critique is that your forms are a bit too wobbly and loose, despite the forces are a bit more bolder and broader, and overplaid. Would you kindly construct out the lines and spaces with 30 minutes of 2 minute quick attitude drawings? (15 of 'em)
The reason is as a result, you'd be able to improve your understanding of your body constructions and silhouettes, and lines of action. Good luck to you, and I hope you've found these completely and defintely beneficial.
