The photo, in my opinion, has been captured at a slightly different point during your jump. To me it looks more like he's already starting the descent of his arc, whereas the rest of the horses look to be on the ascent.
What I would do, were I you and worried about his neatness over fences, is start doing some grid work with him. One exercise my coach set up recently is really good for getting a horse to be a little more clever and quick with their front end.
Set up three jumps, oxer, vertical, to an oxer. Both oxers should be square (front and back rails the same height). From the first oxer to the vertical is 10 feet with a placing pole in the center, from the vertical to the second oxer is also 10 feet with a placing rail. Before the first and after the last oxer should be a placing rail at 9 feet. You can jump this in both directions. Treat the placing poles at the beginning and end as another "jump." Basically you want the horse to get to teh base of the first pole, jump the oxer in with the same amount of power, one stride over the pole, over the vertical, one stride over the second pole, over the oxer, and then out over the last placing rail. Not only will it teach them to be quick with their feet but it will help teach you and your horse how to maintain power and balance throughout the exercise.
I hope that all made sense. I'm exhausted, lol.
