I think a lot of your "flaws" are a hold over from the saddleseat training- you look like how my mom looked when she got on my hunter pony when I was a kid and that is how she was trained.
My first thought is that your stirrups are much too short, which pushes you into a position where your seat is too far back, even as your upper body is tilted slightly forward. You need to open your hip so your upper body is straight (think of a string from your head, going straight to the ceiling), neither leaning forward (as you are doing in the latter pics) or leaning somewhat backward (which you are doing int he first couple pics.) Lengthening your stirrups a couple holes should help you to more easily get into the correct position and better wrap your legs around your horse. It should also allow you to turn your toes in a bit. On the pinto, it looks like your saddle might be a little on the small side for you - going up half an inch or so will allow you to sit into the saddle more comfortably.
You definitely have some high piano hands going - try turning your thumbs up and lowering your hand carriage a little, then widening them somewhat so that they are just above and to either side of the withers, rather than high and several inches up the horse's neck. That will also help to relax what seems to be a somewhat severe hold on your horses' mouths.
All that said, you look good. Just think of stretching down from your hip down and up from your seatbone up, soften your hands a little, and you should be more or less right where you need to be. :)
I really like your morgan by the way - he's quite a looker :)
