I can't help with conformation or anything, but I LOVE his color/marking. Hopefully someone else can give you some better insight, but I do know a picture squared up and from the side would be easier for others to give you critique
Beautiful horse! He looks a bit out of shape, but with some riding, and training, he can get back into shape. Looks to have nice legs, can't really tell on conformation. Nice neck, small head, good conformation, from what I can see.
Oooooooo I love!!! His confirmation looks great from what I can tell at that angle and I like him a bit chunky lol once it turns into muscle he'll be quite the looker! Love the way he holds himself and his expression and of course I'm a bit partial to his markings
