I could MAYBE see Morgan, but honestly I think just mixed breed pony. Maybe some QH, maybe some welsh back there, maybe Paso.. I just don't see anything that screams Morgan at all, or any breed really. Just an all around pony. I COULD see QH crossed to a leaning-towards-Polish type Arab. The color your guy is (light bay) is just not common at all in Morgans. I also see some pangare on your guy which might suggest Haflinger? Morgans don't have it, I've never seen an Arab with it (not to say it doesn't exist), I'm not sure about QHs at all..
Not sure why everyone seems to think everything is a Morgan cross right now lol, they aren't as common as many other breeds.
