Know my Eq isnt that Great! I was trying to brake in my new tall boots ( That was a pain) My leg was all red and sore after (OUCH), We did VERY LOW stuff because she hasnt jumped in awhile plus she has ringbone and I don't want to jump her to high until she gets back onto a schedule. But Feel free to critique.
PS: Sorry she is so dirty!! She likes the Mud lol. White+Mud= Yucky, not pretty coat!!Lol! =)
1) Vid #1 - STOP RIDING WITH YOUR BODY - see how you're pumping with your upper body? Don't. Keep it quiet. You're riding so much harder than you need to! Sorry this is my BIGGEST riding pet peeve!! You had a couple of good strides after the fence, but then you went back to pumping...? In the second video, you didn't pump at all until closer to the end... why? I'm curious as to why people pump with their upper bodies.
2) Bend your elbows and keep them to your sides
Other than that, I didn't see anything overly obviously wrong, you look good for the height you're doing. You and Shadowplay are a good match!
I agree with the pumping. That was the biggest fault I saw. Your eyes were up, you didn't over jump. Overall I think when you quiet your upper body down, you will be a beautiful rider. Lots of talent. Just relax, roll your shoulders back, and stick your butt to that saddle. :) If you stop pumping your whole body won't move so much. I can see your legs moving around a bit, and it's all because of your upper body.
I look forward to see you advance! I also agree that your arms need bend. Look at some pictures then compare to you. You'll see the ones with pretty equitation have their elbows bent and at your side.
