Overall, he is very well-balanced and uphill - the nicest horse I've seen here in a long time
I love his bone, nice legs and good-size feet, nice long neck w/good attachment. Large but slightly steep shoulder . Big withers but not terrible, with a great back and strong well-built hind. He should be able to do anything you point him toward.
Beautiful boy - lucky you!
ETA just saw the vid. Keep doing lots of circles and serpentines with lots of transitions. You want to open up his stride more, get more trot without more speed or tension. (I know, easy to say
) He has much more trot in there, so you want to keep the rhythm, increase relaxation, and ride more forward. If you haven't already started leg yields, I'd start now - LY off the outside leg performed on the rail/track, spiralling out on a circle, and LY from quarter line to track. They will help him stretch and gain more flexion in his leg joints, thus increasing the size of his stride.
Keep visualizing him with a full and telescoping neck as you work http://vichorse.com/forum/index.php?...7715&private=0

Ride more back to front, don't worry so much about head/neck. Remember your training pyramid.
