I was going to do a full on list critique, but I really can't find anything I don't like... other than needing more topline ;)
It's hard to judge much with tack on like that (I have no idea why people do that...) Anyways, he's cute.. I'll give a better critique if you can find a picture without tack!
"Prince Kasper: Beautiful 5 year old 15.2 hand Blood bay stallion gelding (he has been gelded). "Kasper" has recuperated from a fracture in the knee beautifully, and is ready to go onto his new home. Impeccable manners, and beautiful conformation with a lovely trot and balanced, uphill canter."
