The 'Character Mega Reference Bundle' from Grafit has both male and female poses, are entirely full-body, and have a lot of action shots, including jumping and falling.

Timed session. I'm getting better at these.

Had some issues with my computer not wanting to cooperate, so it was slow...but I got them done. The cube and square and the red ball I used the color picker on them; on the weird shapes, I zoomed in next to the color I wanted and physically matched the color to it.

I combined a horse, a cheetah, and a hawk to make this fierce creature.

Did two studies, one B&W and one color. I'm confident in my tools, but I'm trying to grasp shading that will actually suggest a form.
