Both riders are to heavy in the hands for a reiner as well as with that bit ... let go of her face!
A spin is a fwd motion and from the pictures it looks like she is being pulled back and around (i am not 100% sure and it is hard to tell with a picture)...
The stop should be where the rider plants it's butt and whoa into the ground- you shouldn't have to pull.
Your Mare is cute but i can't say that the rider is doing much help(sit up and back to the rider in the black shirt- she is not 2 pointing over a jump). Sorry if that sounds harsh but i want to be honest with you.
