I'm not sure what you are looking for, or what kind of training he's had etc. From what I can see his paces aren't bad, he rushes a lot, like runs into the canter, even the trot is a bit running, rather than straight of the aids. He seems stiff in his movements, like not fluid or flexing around the corners.
I can't really tell much for conformation from the video quality, but he seems a bit overweight and has a largeish head? That might just be me. Could be wrong, don't have much experience with QH, which I presume he is, or something similar.
Thanks he is belgin/QH that's where he gets the big head. Yah I can see that about his running into the canter and is stiff. I don't know if that is anxioty or what.
But couldnt the stuff you mention be worked on?
He is a really lovely looking boy. I couldn't help but notice something slight with has back leg in the walk im not sure how to describe but he has almost a slight pause or a sliffness, im guesssing it's comng fom the hip but im no expert just saw it in the walk.
Don't know what your intending on doing with him but he's very nice just needs a bit of educating. Have you ridden him?
Good Luck I bet he's a real sweet Heart
How old is he? He looks quite green. The rushing into the canter like that and breaking gait could be lack of balance, simply due to lack of training...which could certainly be worked with. I really like his reaching walk, and he looks very kind.
