I agree that the work is great. I also agree that the legs and hooves need a bit of work. The legs look heavy, giving a draft horse appearance. Perhaps that is the look you want, but if not, they should be thinner. The hooves look like a mad farrier ground the toes off. Check the reference photos. But still.... very nice!! Regards,
At such a speed, the ears should turn a bit backwards and the head is too high in the air. Usually the back is moving a bit more up and down. The tact doesn´t seem right either...
