One thing I noticed consistently in those stills is I would personally like to see a smidgen more release so your horse can stretch down and properly utilize his back over the jumps. He looks fantastic already, but while his neck is round, his back is rather flat and he's really having to work to his throw his shoulders over the jump.
You look like you pitch with your knees which results in not only your toe turing out, but also you entire lower leg. Like a previous poster said, having you toe turned slightly is not necessarily a bad
thing while jumping, but you should continue to have consistent contact with your calf. If you can teach you leg to stretch down and around your horses barrel rather than gripping with your knees, you will also find that you leg will be stronger and quieter (so it wouldn't drop behind you while jumping) and support you upper-body more effectively as you are slightly in front of your horses COB making his job that much more difficult.
Also - watch those piano hands on the flat!
Other than that, you look like a very solid and confident rider and you horse is gorgeous! Good luck! :)
