5th picture: near hind almost looking like a Paso pasturn
probably just a bad angle or something I hope.
Over all he is a beauty. Nice colour, strong presence, maybe a little high in the withers but with that head, neck and a correctly placed saddle you'd never know. I bet he'll ride smooth too.
Good choice to geld him too. He is a nice looking boy but 9 times out of 20 I'd opt for gelding.
Congrats on your boy. Happy trails..er...Jumps.
