This is not bad for one of your first. I still have this issue myself when doing gesture, but watching different methods makes me more accepting of the things I do. I recommend taking your time. Maybe 5+ minutes per pose just so you can focus on each line of the pose.
Secondly, try using a smaller brush.
Thirdly, watch some videos on different peoples process. I recommend: Michael Hampton, Proko or even Love life drawing.

Keep up the good work. Looking forward to seeing more.

nice work. You even had time to do some shading on a few. Were those done in 1 minute as well or more.

I'm having trouble logging in, so I'll just dump all at once the ones I did so far. The time I took varied between 30 seconds to 1 minutes and I used my left hand as I like to make myself suffer... Actually I just want to train it a little bit.

Liked for the drawings and the suffering.
