Hey :) Good stuff, but I think it'd be a more approachable to critique you if you did just a few poses to post, like maybe your 5 best ones.

I think it would be helpful to practice landmarking. There's a lot of energy here but some of the angles could use more direction. There's a lot of tension in the arm connected to the ground, for instance. Accuracy isn't the point of a gesture drawing but some amount helps the human brain more easily see a person. I like Marco's points about adding plumb lines to tether parts of the body to each other while remaining loose.
