Okay here is somthing that will, help! imgine you have a cord from your5 chest pulling you up. remember should back (also will help more bend in your arms) but with the cord, think you to makea line with your bodey, hip, to ankle and this will help you close your hip angle and put you in better 2 point postions as well as correct you leg from were it is now.
Things i see to really work on with you bodey:
1. close your hip angle
2. knees forward not like your squating and not pinching the saddle with your knees ;P (will help you hip and lower leg)
3. Toes forward heels down withthe your bodey waight balencing.
4. open your shoulders, chest a tad bit more, but really good job looking were you are going!
You look really good, Once you get this down your horse will be able to jump with you not getting left behind, I think if you were to do samm grid work it could help you and your horse alot! All it is, is practice practice practice! I dont see anything terably wrong with this picture, but Im sure we could really help you alot better with a. more pictures. b. better quilty of the picture.
Your horse looks like fun!
Good job and keep up the good work!
