To me he definitely has the TWH look. I've ridden Walkers that indeed not only did the runningwalk, but would trot, pace, stepping pace, rack, speed rack, one even did a likeness to the foxtrot!
I've met many 5-gaited Walkers :) Even my guy can do a rack at low speeds, and trot too.
He looks lovely btw, I love his color. He actually looks quite a lot like my horse! ;D
