figure drawing practice

Hello community, its been a while since i uploaded something, so i thought its time to change that. These are my 30 sec. figure drawings of today and i would be happy to receive critique on them. I also uploaded picture of 1 min. and 5 min. poses, feel free to critque either. My current goal is : Better understand human anatomy, so I can render imagined poses. Regrettably i could not keep up my drawing rutine in the past 3 weeks and skipped practise sometimes, but i am happy to have hit a 5 days streek now and ill do my best to keep going at it. thanks for your time and have a nice day,
