He looks more western to me I think because he's chunkier and low, rather than leaner muscle and more upright, for lack of a better description. He's got a nice built western horse type hind end. I think his best feature. Also could be just the way he is standing, but he appears to be ever so slightly sickle hocked, not enough that I would consider a fault but I notice WP type horses having this same confo. I heard it can make for a smoother ride. His neck ties in low at his shoulder, reminds me of a western horse as well. This is just my opinion, not saying that is how western horses are, just what makes ME think western.
