I think he's lovely for a horse who's barely had any training. Sure doesn't seem that way.
As for english movement? If he picked up that easily on breaking, he won't have issues with english training I'm sure. This video is hard to judge because the gaits you showed us what he will be like with some english riding but you'll want a much more forward set of gaits and more compact and put together, engaged from hind end. If you want to show him, how you ride him will change but as a western pleasure type horse, he looks like he would be a blast to ride.
