Seeking Critique on Gestures #2

Hi everyone, I'm back again! I'm once again asking for critiques on my gestures. Taking Aunt Herbert's advice on how to construct and ultimately draw gestures. I believe I have improved, however, the three things that I am definitely struggling with are: proportions, how to draw the gestures more quickly (completed within 2 minutes), and how to imagine the 3d shapes in the gesture. I've been going at this every day for 30 minutes now. I would love some more criticism so I may improve. I have also been trying to clean up my lines and make my line confidence/ quality better. 

I've done 15 poses within the timespan of 2 minutes for each pose.

Hello BillyJones ! I'm a beginner so I don't know if my insights will be enlightening.

The positive side is that the poses are correct, we get what the character is doing and how it's positioned. The one throwing the brick is the one I prefer. I really get a sense of dynamism from this one. The other one is that you are self conscious enough to point things where you can improve which is an underrated skill imo. 2 min for a pose is great !

Proportion wise : your torsos to waists ratio don't look correct to me, there's too much space between the two. I think it gives an elongated belly to your characters but I'm no specialist.

Either way : You got this !
