My Gesture Drawing Progression

Hello! This is my first time posting stuff here -- I've been on and off on doing gesture drawings until lately, I want to continue to do these more often. 

I very much appreciate it for any comments as I do want another pair of eyes and see what I can improve . . .'cuz well, I don't know if I'm doing it "right."

Most of them are just 1 minute and 2 minute gestures

I'll continue bumping this thread to showcase my progression

Okay, not exactly happy with this round -- both my thumb and wrist started to tingle during my session
Again, 1min and 2min gestures

Today, I decide to rollback to 30-second gestures just to push myself a bit all because . . .my linework is yet to be desired.
And I included a sanguine-colored stroke to show how I perceive the line of action as an afterthought.

As you could tell . . .I struggle on 30-seconds
