Lovely looking horse :) My WB is strong but never nasty when jumping, But if I 'pop' her over a jump under, say 2 foot then she don't batter a eyelid and don't put much effort into it. The min I put the jumps up, the higher the jump, the bolder and better she jumps. She jumps 5 foot plus with ease :)
My girl is a great all rounder, And I think the more schooling and the better the rider the better the horse becomes. A horse needs as much trust in the rider as the rider needs in the horse :)
He looks like he's pretty nice.. but he'd go better if ridden by a more experienced rider. So basically what ChingazMyBoy said.
I also wouldn't want to be stuck in their class at a show (as I'm guessing this is a small class at a local show during the first part of the video).. everyone is all over the ring and cutting off corners. I had somebody do that at a slightly bigger show that I went to this year and it drove me up the wall as they continually cut many riders off.
