Overall porportion seems pretty even, It's hard to tell about the length of neck, but I'd say it's not too long. Neck is set medium height, and of a good width/muscling. A nice sloping shoulder of a good length. Good length of the upper arm, but this horse looks tied in below the knee. Pasterns are a bit long and they are a bit flat. I like the length of back on this horse, might be a smidge long. This horse appears to stand camped out behind. The pastern angle on the hind leg does not match that of the front leg, it's much steeper. (this could be the footing or maybe shoeing? It's hard to see) Overall I would not peg this horse as a high performance horse (English or Western) because of the long/sloping front pasterns and the very upright hind pasterns. He should have a nice smooth stride because of the sloping shoulder but the camped out hind legs might make tracking up and achieving collection difficult. I'd say he'd be a good lower level dressage/trail horse. (I don't know much about the western events but I don't think WP wants long strides and I wouldn't peg him for speed events?)
Overall this horse gives a very good impression. Evenly porportioned on the large scale, he has only a very slight uphill balance. The neck is set high on his shoulder, which is sloping (50-55 degrees?). Nice forearm, but his pasterns are a tad long and flat. Medium/long back, medium length loin. The "triangle" in the hindquarters is equilateral, with all sides even. A high stifle indicates a lack of jumping scope. Nice dropped hocks, although he appears to toe out slightly behind. Relatively flat croup. I would peg this horse for dressage, maybe hunters. He should have a long stride due to the shoulder, and good collection faculties due to the angles of the hindquarter. Might not be as scopey due to the stifle placement. Should be light on the forehand because of the high neck set, but his lack of true uphill balance steers him away from high level jumping.
Thanks in advance!
