Done as part of a 30 minute class.
My current goal is: I don't know! I am an absolute beginner; I'm here to study the basics of rendering
Greatest job on your hands, SINE!! Very powerful gestures!
But I've got one tinier, littlest bit of advice: I love how much the hilarity of the attitudes of those gestures, but I just don't and can't get enough of it. Why don't you please loosen up more with 149 more minutes of 19 second gestures??????????? (149 x 60/19, 8940/19=471 warm-up drawings of those hands)
And the reason why????????????????????? It's as a result, your hand gestures will be able to tell funny stories and communicate funnier cartoons and caricatures, even though it's gonna just a bunch of spontaneous scribbles; that's OK.
Good luck with this suggestion, and I hope you've found it completely and totally useful, supportive, and advantageous.

I lilke that none of your straight lines are straight! Weird right? They all have a little curve to them. This really makes a more natural, flowing drawing. I'm guessing you did this digitally? If so, (even if not!) don't be afraid to make the entire shape of the hand first and then cut in the details. You might have done this and erased it or did it on an underlying page and cleared it. The basic shape is the foundation of the drawing.
