Looks nice and healthy! Great choice, hornbeam are fun to work with. I agree that they are a bit tall for themselves, but as long as the taper is good, (hard to tell from the photos) and there is enough differentiation in size between the trunks, I'm not sure that it's that big of a problem. I would be more concerned with getting the base straightened out. You'll need to work on those roots next year when you repot. I would put this in a larger wider pot. I keep my hornbeam in a slightly deeper pot than I normally would for other types, they do seem to like the depth. And remember that these are understory trees, so harsh afternoon sun in the hot parts of summer should be avoided. The appear to have nice harmonious movement, happy new tree Jarrod!
