He looks downhill in the first picture, not so much in the second. I know from taking pictures of my own horses that you can make a horse look really awful by just taking a couple steps left or right, up or down. So I wouldn't read too much into even the downhill appearance until you see him in person.
Other than that, he looks pretty normal.
I will beg to differ tinyliny on the downhill feel.......I can definitely feel that riding western. All I have ever ridden is western and I hate riding a horse that feels downhill. Hurts my back too. It can be made better or worse depending on how the saddle fits. Wide saddle plus downhill horse equals murder on my spine! That's actually one of my biggest Quarter Horse pet peeves.......downhill and also small bones and feet on a LOT of them.
But I won't even say bad things about this pretty Paint because I know how I can take 10 photos and 5 will make my horse look wonky in ways she isn't in real life.
