This guy looks really nice :)
My old horse judging coach used to say its really hard to tell the difference between a nice draft and a fat draft. So everyone shows their drafts fat unless they have great conformation.
That said, he does look good to me but that may only be because he's chunky ;) He's got nice thick straight legs, a short back, a big thick neck, and a good shoulder- the things Drafts are bred for. The thing I would say is his biggest flaw is his shoulder is not sloped enough- bringing his wither to far forward. But again that is a common Draft characteristic so it just depends what you want to use him for.
