I spent about 1 hour on this gesture doodle. I found it really fun using Photoshop's group/merge group, duplicate layer and free transform tools. Basically the free transform tool allowed me to work on sketch at any scale and still i could shrink it so it wouldnt cover the whole work space. The duplicate tool was really helpful to be able to experiment with idea while not losing originals. The merge group allowed to get quick preview of work. And the group tool helped to make it easier to hide and show stuff.
I found it fun drawing movement here with a skateboard and basketball, as well as trying out an insect looking thing for the first time.
Hope you find this helpful.
