Yes, the rider is very harsh and demanding. The Mexican saddle makes me think he might be of Mexican heritage. They ride oftimes very harshly there. They expect instant obedience and sometimes use pretty harsh spurs, and bits. Not to say all do this at all, and they have some really amazingly trained and high quality horses their, too.
That horse strikes me as the one who has been trained to "jump now and ask how high on the way up, or else!"
He looks to be really nicely put together, tho. He is a bit light of bone, but is he is Mexican bred, he might also be very sturdy and agile.
