It's really hard to critique the pictures you posted. The horse is not standing square, and the camera angle is not straight on. I'd also like to see a picture from behind the horse, and in front of the horse.
Can't tell how long her neck is when her head is turned. Her back is long and the angle of the pictures (head turned) makes it look super long. I'd like to see more rounding and more muscling on the top of the hindquarters. Her shoulders look heavy in comparison to her hind end.
Front legs look okay. I like her short cannon bones. Hocks are cow-hocked and I"d like to see the gaskin more well-muscled. I like how low her hocks are. (in contrast to lilruffian)
Overall, not bad.
I like her head.
