To me he looks like a Hunter (as in Hunter Undersaddle, or field hunter) or maybe low level eventing, rather than a dressage horse. Though that would depend on his jumping ability. I like his bone, solid boy, looks dependable, what I would look for if I was after a field hunter, though most likely he could turn a hand at anything.
These opinions are from a NZ point of view and I don't know what the equivalent where you are, if you aren't NZ would be :)
Also does he have clydie in him? What is his breed?
