You've managed to consistently capture a lot of energy in these sketches, very nice! However, there is still some stiff qualities that I noticed, specifically in the shoulders. I like to bein my figure drawings by starting with the shape of the shoulders. Considering things like: do they droop down, do they curl up in a 'u' shape, does one lay slightly higher/lower from the other? Additionally, doing this gives me a good landmark to work with when considering proportions.
Good work, hope this helps.
