Back is a bit long and swayed. He needs HILL work or cavelletti to increase his abdominal strength to support his back. He is long backed. His neck is set low and is too long.. and over all he will have trouble balancing to the rear and working off his hindquarters. I expect he is heavy on the forehand.
He has good bone and his shoulder is OK but the angle at the point of shoulder is not very open so he may not get his knees up over fences. His knees seem a bit offset and he stands close (looking at him front the front). He might interfere at the trot (probably not since his legs look clean.. but hairy LOL).
He has nice bone and the hind leg looks like it might be a little straight. I like his low hocks.
He will probably do OK in low level eventing.. low jumps and not a lot of dressage demands. It will be good for him and you will learn a lot on this horse.
