There are a couple of things that concern me and stand out to me about these photos.
First, you are definitely snapping back in the air and/or sitting down too soon, and it's causing your horse to jump very flat and be very defensive. In photos 1, 4 and 6 you can see this quite clearly, photo one shows your horse with a very grumpy, defensive expression. Your weight should be out of the saddle and in your two point until the horse's hind feet land. You might want to put a placement rail on the landing side of the fence and practice holding your two point until your horse crosses the placement rail. I believe you'll find your horse's roundness and attitude improving if you learn to hold your two poingt through the landing stride. Your sensation that you don't need to be in two point comes from the fact that your mare jumps very flat and hollow, probably in defense - the more you're diligent about staying off her back, the more she'll start to use herself better and round. If you continue this way, I think eventually you'll start to have cheap rails behind.
Second thing that concerns me is the open fingers in photos 2,3, and 5. Usually this is a "soft" habit; exhibited by riders who are trying very hard not to restrict the horse's head and neck, but it's also quite dangerous - *very* easy to jam or break a finger on landing, and very easy to drop a rein. Softness and your release comes from your shoulder and elbow, not from your fingers, so close your fingers on your reins and work more on following from your elbow and shoulder.
Finally, you're riding in a leverage bit, with no snaffle rein, and a martingale on the curb rein. Yikes! Please, at the very least, put a snaffle rein on your three ring bit, put the martingale on the snafffle rein, and only engage the curb rein when necessary. With the set up you have now, you're constantly engaging the leverage action of the bit whether you need it or not; and there's no reward or release for your mare when she softens. Nothing about these photos indicate your mare's so hot that this is the only way she can be ridden.
By now you're asking "Doesn't this lady have anything nice to say? Jeez!" Well, yes, actually, I do! You're clearly a very able, athletic rider: your lower leg and base of support is excellent, though I'd like to refine your stirrup position a little, in photo 3, you're exactly in the middle of your mare, in textbook position, with an admirable flat, relaxed back and eye focused up. Other than the open fingers, it's a lovely photo. Your mare looks like a blast to ride and has plently of jump and a wonderful front end over the fences. I would love to see you work on some of the problems I've mentioned and add some polish to your riding; that would be something to see!
