This is a fun video to watch. The horse appears to have a little problem with the bit, but the rider does not seem to be keeping a lot of contact on the reins, so that's good. She is comfortable enough to drop the reins (altho Reynir drops the tolt and goes into trot; he may need the contact to be able to perform the gait).
It is very nice to see the much looser rein, and less heavy contact.
