Drawing Hands, a 10-Day Challenge!

I started this challenge with the goal to drastically improve drawings of hands through continuous study and practice of anatomy and style. It was a great experience, and if you want to improve your hand drawing I highly recommend it! See details of the challenge below.
Update: a detailed tutorial on how to draw hands based on this challange is now posted here.
Reference Pinterest board for this challenge:

Rules: there is no mandatory drawing count for this challenge, instead try to draw for ten days in a row and try to draw as many hands per day as you can.
This way there is a bit less pressure and it’s not as overwhelming but the continuity of drawing daily should be really good for you! Use the Pinterest board or your own reference. Use tags #artwithgvaat and #10daygvaat !
