I'd love to see Hercules in a photo beside an average 14-15 hand mustang just for comparison! Please post a picture of him when he's all shed out and shiny. Do you think his height comes from draft blood in his background? He doesn't look exactly like a draft horse descendant.
I'd love to have a mustang, but as a beginning dressage rider I think I'll probably have to go for some more typical breed or cross-breed. Some 'stangs are suitable for the discipline but many just aren't. Besides, there's the whole (human) attitude thing to deal with. Can you just see a cute little wonky-colored mustang in a barn full of huge bay warmbloods?
