Okay I'm just going to start out by saying I absolutely love your horse! What a cutie!!
Anyhoodle, for a critique..
I realize this is a jumper round, so it is important for speed (obv.) But there is a difference between a good speed, and an uncontrolled speed. Phoebe seems very strung out and almost uncomfortable in her surroundings. I'm assuming this show was an off-property show, as in you went away to it, because she seems a little distracted at times. But when she is paying attention, she is just tearing up that course!! Lol . Your need to relax your body in these situations, like mentioned by others, to let her relax. And to help you out a little with that counterbending, you should really use that inside leg on her, and bend her with your inside rein. If she is not responding, lift your inside rein a tad bit in an upward direction to 'pick her up'.
Now from the beginning of the course to the end, I could just feel the tension building and building. You began to tense up a lot and after about the second or third jump, you were not giving her any release at all! Which was affecting her jumping, and her way of moving about the course in general. Before the jump, you need to take a big breath and loosen up a little. Sink your heels and lock them around her barrel at the girth. And your release should be at least halfway up her neck. I think I stopped it at 1:16 or something like that, and it shows you two, mid-jump. She looks like she is trying to stretch her neck down and tighten up your knees, but you haven't given her any release and so she has held back, and tensed up a lot.
But enough about the negative, lets talk about the positive! You have a nice way of jumping other than your leg and release problems. You have a good flat back and are attentive and looking to your next jump. Your horse has a good jumping style. She is athletic and spunky! Her hind legs leave the ground evenly pushing off and she is trying to round out over the jumps and tighten up her knees.
So again, I really stress the importance of that release. And just relax for goodness sakes!! LOL
Beautiful horse though and a lovely clear round! :)
Sorry if I come off as a tough critiquer though, but whats a critique if I only tell you what you're doing right? Haha
