That is a CUTE horse, pony, horse?
I'm not very good with conformation, but in the second and fourth picture (especially in the second) she looks skinnier and her proportions like kind of off. Her neck looks kind of big compared to her body size, whereas in the other two pictures she looks proportionate to me.
Anyway, I don't normally comment on conformation threads, but this horse/pony could be the sister of a palomino Welsh/QH cross someone at my old barn used to ride. She was/is an AMAZING jumper, could pop over a four-foot fence no problem.
Here's a video if you're curious:
