In my opinion, he's quite a handsome boy. I'm not an expert, but this is what I see: Average length of pasterns with angles that match his shoulder, straight front legs, long forearm with short canons in the front and possibly back at the knee. His back canons look a bit long. His girth looks to have decent depth, nice big shoulder with a good angle, good length of back, lovely hip with a well-sloped croup, although I feel like it could be a bit bigger to match his shoulder more. His neck looks to be set on nicely and his withers look well laid back. Overall, he looks very balanced through his body, with good bone and an uphill build- I can see how he'd be a good jumper. A few things that stand out to me are his back legs, I'm not sure why but they don't look quite right... I'm guessing his feet have something to do with it, he doesn't seem to have a lot of heel and his toes look a bit long. His fetlocks might be set a bit high and his hocks seem a bit straight to me. I'd love to hear what others have to say about his conformation... if I've said anything grotesquely stupid, someone please set me straight, lol.
Overall, I really do think he's a very good looking horse!
