At both the jog and lope (but mainly the jog), he needs to drive up underneath himself more with his legs. He's pulling himself along more with the front end. I would work on setting his head, taking up some light contact, then using your legs to really drive his hind end under him. He might speed up a little bit at first, but keep working and it will improve.
He has a very rhythmic lope, an uses himself fairly well with some elevation of his shoulders. All good things. He could drive up underneath with that hind end some more, but it's not bad (and actually better than the jog). Maybe a little fast, but don't slow him down to the point where you lose that nice rhythmic cadence. In AQHA, slightly faster with good rhythm/cadence is better than slower but strung-out.
I agree with an above poster. At the trot, he is off. Can't tell for sure, but I was thinking right hind or left front. He's not shorting his stride any, but see how he has that little hop and head bob throughout. That is really indicative of a horse that is off. Doesn't show up anywhere else, though. Other than that, I actually like his trot. Try to learn to sit that trot, as a lot of shows ask for an extended jog in WP - it shouldn't be out that much, kinda 1/2 way between your jog and trot (although it is nice of a horsemanship extended jog)
Best of luck to you.
