Definitley looks like a hunter to me....
What are you planning to do as far as "western" goes? Pleasure riding? Games? Cow work? That would help us get a more general idea on what you are looking to use the horse for. :)
He would probably do OK.. but he will have a long stride and not move flat knee'd like they want in Western Pleasure. Trail he may or may not do.. that is a trainer and horse thing. Gaming would be tough.. too tall and too long strided.
He still looks like a hunter. I would like to see him learn to jump and collect and so forth and maybe go in the 3' class. He is a pretty nice horse. He has the look of one that could go pretty far if he is sound.
