Very nice for the first time! Obviously his headset needs wprk (especially at the walk) but it looked like he was just so excited by all the commotion he wasn't focusing enough to collect. His trot was beautiful when he calmed down and rounded up, nicely forward! He has such a pretty high head-set, have you thought of doing dressage with him? The transition from canter to walk was rough, but again he just looked like he was really excited by everything. All in all, I think he'll be FANTASTIC as shows once he's been to some more and calms down at them.
To whoever is was talking in the video, I also call my horse a pony, even though he's giant and built like a line-backer.
