Critique on my gestures (30 seconds)

Finally decided it was time to step out of my shell and ask for feedback. 
would love any advice on how to improve my gestures and some tips on how to lower the amount of lines I use.

These are amazing! I love the dynamism and expression you put into these. Keep it up!

Really big fan of the 'generalized' nature of these sketches, the direction and placement of everything looks pretty good, and captures the essence of the pose. 

I would try to add a bit more purpose to your sketches. I understand that's hard to do with a time constraint, but taking a bit more time to try to figure out the overall placement and proportion of things will benefit more than just your gestures overtime. As it stands, these look somewhat hurried, which can contribute a lot to the general feel of a sketch but could also be improved on.
