This is Arty (aka Heartbaby).
She’s a young PMU mare, I think around 6 years old, and a solid novice-level event horse, almost ready to move up to training. I get to ride her sometimes.
When I have the chance, I video myself riding Arty so I can see what all I’m doing wrong. Luckily for me, she’s pretty tolerant.
I’ll post more pictures of her when I have them.
