Nicest job on our gestures done quickly, Khj2005413, those are mighty terrific indeed! Please keep on pushing your gestures far in your next session. I think it's perfectly normal, as King1 says, to have all your lines not as precisely flowing as we want them to, so there's no need to be down on yourself. Practice makes progress, but progress makes myelin, but myelin makes perfect.
When it comes to constructive critisim, here's where they stand. I'm not getting enough of those loose and light gestural lines. Would you please free up your brains and hands with 10 minutes of 29 second quick sketches with our custom timer? As a result, your lines, as I've implied will become the most exact in their loose and light touch to your figures' forces. For more info and details, please look into a Mattesi book on Figure drawing and some Youtube videos online. Let's hope they have been helpful, encouraging, and educational.
