Hey these aren't bad for a first try I would highly suggest you check out Michael Mattesi videos on force gesture drawing there done In a different style then proko but they really helped me see the rhythm and flow of poses I would also suggest since you're new to gesture drawing to try longer times to draw gestures like 1 to 5 minutes for now and once you get more used to that you can go back and try the 30 second videos In terms of a critic I could give you the lines are too straight try using C and S curves for the body Gesture drawing is hard but keep at it and you'll improve keep at it
