Both are very cute and move very nicely.
In terms of a critique:
#1 You stand quite a bit in your stirrups. You need to work your thighs and knees a whole lot more. Particularly in your jumping shots with Lila you can really see how much you are standing in your stirrups, not only by your feet but also by your body shape and the position you hold yourself in as you jump.
#2 On the good side of things, you seem to do a generally good job of allowing the horse to move forward, terrific give on your reins!
#3 You need to gain some confidence in those shoulders! You really need to work on rolling them down and back, you have some hunching issues and it affects your arms as well.
#4Particularly in your shots at the canter with Chloe, you REALLY brace wiht your seat. You need to shift this to using your abs effectively. In both shots you are really bracing with your seat and in the one your feet are way out in front of you, so you can tell how much you doing it. Try to tighten your ab muscles, like you needed to do a sit up, this will draw your focus there and allow you to find your center of balance instead of fighting the motion of the horse. If you can use your center of balance in terms of tightening the abs, stretching up in your torso and dropping your shoulders down and back you will find it much easier to use your body effectively rather than having to try to go up against the natural movement of the horse's gait.
You look like you need some no stirrup work to me. Strengthen your legs and work on your balance. You will be great as you look great with your horses.
