Thank you everyone for the tips/critques :) I'd love to think he's perfect, but don't want to be blind to it :) I know also alot of his weight gained needed is in muscle. But it just doesn't show how ribby he is in the pictures :(. Also doesn't show his spine, either. I know its good to feel ribs, but you shouldn't be able to count them. We do alot of controlled trotting and stopping/nice turns to build up muscle, on a lunge or the round pen, cause he has a horrible trot to sit, lol. And I don't think he's ready to do those thing with me on him yet.
But he has come a super long way, and I love him dearly. I am glad to know that he really is a pretty nice horse, and its not my imagination lol.
