From what I can see (not such good critique photos) he has a really nicely balanced body ratio (neck to back to overall length). His hindquarters are good, nice pelvic angle and length and rear canon is squareed up well. It's a bit long (hocks on the high side) but is well formed. Gaskin could be stronger, a bit thin.
Knees are good, not behind, not over . .just right. Pastern lenght is also balanced and angle too is good. Throatlatch is a bit thick and kind of heavy head, but I actually like that look, personally. His shoulder is the upright one of a fresian, so wonder if his gate is a bit heavy or choppy?
Overall, he is built to last and has beauty to boot!
