Starting at the head.
Not a bad head. His mouth is deeper than I like, and I do wish he had a larger eye. His throatlatch is not as clean as I would like, and his ears are nearly set on top of his throatlatch, meaning he won't have as great of use of his neck and I would have liked to have seen.
He does have a nice neck. But I think you'll have a tough time keeping the fat out of that neck as he's already showing a tendency for a crest.
His shoulder is a bit steep, but he does have a good set of withers.
I like his back.
I would like to see more of a hip on him. He's pretty light. But I think this is a colt, so you might be able to put some muscle on him thru riding, especially backing him up.
To my eye, he would look MUCH better without that fake tail.
He literally hasn't got a gaskin.
In the first pic, he's standing under himself too much. In the 2nd he's out behind himself. I would like to see a correct pic of him without that fake tail to see where he actually does stand.
HIs feet need that toe taken off badly. Let him grow some heel! No heel and long toe, recipe for problems.
Moving up to his front legs. Man oh man, I wish he had some forearm.
In the first pic, he's too thin. In the 2nd pic, he's got more weight, but not more muscle. Is this colt of riding age? Riding him would help him a lot.
He's not a bad looking colt, heavens knows I've seen far worse. But he needs some work. Physical work, riding time, working on a fence to strengthen him up. I think with some time, and work, he would be much better.
