Your Horse is beautiful. Are you going to showing any in the AQHA? They have lots of hunter events. The only thing that I can see that you could do, is to gather her face and collect her a little more. I think she will give you a longer stride that way. ALso, when you are working on the flat, try to keep her topline (headset & back) level. It dosen't matter so much in equitation or jumping, but your definatley don't want her head in the air, it is too easy for her to get away from the bit. You look great and I hope you check out some of the AQHA competition.
