I do have two concerns, though. It seems the horse can be quite strong. The bridling suggests that. The horse is doing simple flat work and low jumps, but is in quite a rig.
Also, the jumping pics bother me. If they picked the best, they sure picked ones showing him hanging his knees a bit more than I would like. The video shows the same hanging tendancy. I tend to avoid "hangers" for upper level eventing for safety reasons.
Go try him and see if you get along.
