What I see is not too bad. Horse had a great rear end (good engine!) and a very strong coupling. Shoulder seems steepish and I suspect the horse is tied in at the knee (but will wait for better photos to say for sure).
One thing for sure, this horse is built VERY downhill.
Looking 4ward to better photos!
I just looked at his pedigree.. LOTS of Halter horse in there...
Anyway....all of the horses in this pedigree were proven winners in the WP pen. The dam of Open Range was a kick butt WP mare....saw her show for years on my AQHA circuit.
OP...I would love to see an under saddle vid if you have one!
