First of all, good job with your gesture and good to notice that you are having fun with gesture.
If I do have one word on your gesture drawing, I think you are trying to get every detail of the pose which is good but not the main point of gesture drawing. Like @snakker said, try to find interest/strong/elegant lines that DEFINE the pose/action itself.
Another minor stuff to say which I also suffer atm is line economy as it looks like you scribbling. Unless it's what you want it that way, it's preferable to keep a clean line economy (e.g. max 10 lines for 30 sec gesture) and just worry about key line.
But looks good so far and good luck!
