There is a great sense of anatomy around the waist and legs, but I see your need to work better with proportions and arms. I would recommend you to sketch an overall view of the image (lightly place the body shape, position and width of limbs) before rendering muscles, bones and such. The initial sketch should be quick, don't put too much effort or thought into it because it can slow you down.

It's important to use construction lines before you go into the details and you did a great job with this I specifically like your shading. Something I would suggest (especially when it comes to quick figure drawing) is to not rely on them. Try to add a kind of organic fluidity into your fast sketches by using long strokes and solid lines rather than the, most of the time messy, short stroked etching with your pencil. It will help your sketches become less stiff and unnatural. And the most important thing to remember is that you need to capture the motion and well "line of action" of your subject. Don't worry about how it's going to turn out. The idea is to achieve an understanding of the movement not whether you get a beautiful perfect piece in the end.

Hope this helped!
