Truthfully, he does show some halter influence (he is just a bit light boned, especially on the front end and his feet are a bit smaller than ideal), but I see more of a classic style bulldog type QH. He's got good angle in his hocks and nicely angled front pasterns whereas halter horses don't. I would definitely want to make sure that he wasn't as downhill as that one picture makes him look, though.
He's a nice looking boy but I would dang sure get him trained up and excelling at some discipline before you ever consider breeding him. Also, just a suggestion, but I would be exceptionally selective of the mares I bred him to. There will be a lot of folks seeking you out to breed their fugly nobreedbutshe'ssweet mares in hopes of a colored foal. You're already going to have enough trouble with people calling you a krazy kolor breeder for getting a....what is he, perlino or cremello?
