First of all - I like how your leg is so solid at the girth.
Second of all - the first course is lovely - the horse is really with you and letting you ride to the fences, etc.
However, in the second course it looks like he is trying to take over and just do the course himself. This needs to be rectified in the warm up - while you are handling it well in the ring. How I would go about doing this is after you have started to feel this over the warm up fences - take a step back and work on the bend and transitions - use your fingers to feel his mouth, raise the inside hand and start to work on the outside leg to inside rein connection to get him infront of your leg and listening. Transitions in this bent frame (ie where you can see the inside eye with your inside leg at the girth) where the horse remains the same in the frame is what is really going to get him back to you. While he is straight, his neck and barrel are locked against your rein and leg aids respectively - making it possible for him to grab onto the bit and go. I like how you deal with this when he does - by simply feeling with the fingers - however your leg and seat need to get involved to get the barrel looser and more responsive to your leg and to allow you to have more control over the hindlegs and shoulders.
Overall you are a nice rider and I think you are dealing well with things that are cropping up in the ring - your equitation is solid and you are a great show rider. Now it is time to learn to rectify some of these things in the warm up and start training the horse. Good luck!
