It looks like your lower leg stays put at the girth and you keep your heels down well. Good! It's kind of hard to tell with your over-the-helmet-head-warmer-thingie, but it looks like your eyes aren't always up and looking where you're going. In a couple of the still photos, it looks like you're looking at your horse's head or at the ground directly in front of you. =) Nice seat though!
Yes, I have a bad habit of looking down at her legs to see if she's on the right lead, even though I can feel it. It took my a long time to stop this for my diagonal(posting) too even though I could feel that as well.
May I make a video suggestion? Have the person filming stand STILL and gently track you with slow movements. This will cut down on the pixel/grain in the video OR pick a corner far post and prop the camera up on the post where it can catch the whole arena. This way it doesn't move at all and you will get a MUCH better quality video that will be easier to critique. Also you can get a cheap tripod at any camera shop for as little as $20. I just bought one because often times I have NO one to film me, just me :)
Your riding looks good though! Sorry I was so hung up on trying to see it (darn graphic arts person I am! LOL) CUTE horse!!!!
I think that you have a nice position and a lovely horse, but when you first went into the canter he seemend to be shouldering out. This can be stopped by holding your outside rein firmly and opening ur inside slightly and appling ur inside leg!!
Ya the saddle always looks like that its because she's small and strangely built...if its any farther back its too far back.
I pooped her out this weekend. She was so out of breath after I gave her a piece of my mind but she was excited to go and a lot more willing!
