That Arab was only jumping very small in those photos so the horse's jumping style there is perfectly fine for that height. You don't *need* the knees snapped up tight until they have more height. He's not going to smash in to the rail unless he's gumby so he doesn't need them tighter than they are now.
As to his head, again, perfectly fine for the height. He's not jumping big so he doesn't have the air time to round out and drop his head like they do over bigger jumps.
My horse jumps exactly the same over little things, but put him over 65cm+ and he tucks his knees up like he's jumping 1m and bascules beautifully because he's actually in the air long enough to.
Each horse jumps differently. Some are hollow and others just naturally round over fences. Doesn't matter the breed.
