he is cute and looks very happy

for you:
-close your fingers on the reins
-make sure you keep those thumbs up (this will help keep those elbows in too)
-toes forward
-i would like to see your heals down more but you are riding dressage so to each his own
-some of the pictures your lower leg is sliding forward and giving you a chair seat try to keep that lower leg under you
- eyes up, i tell my students if you look at the dirt you are going to end up in the dirt

for him:
-i would do lots of stretching and make sure you warm up correctly, this will help him stay supple and keep him sound

good luck!
