The second photo was 2'9, the first time my pony has ever jumped that high! He had some trouble at first but we did get one nice jump (where his take off was pretty good). I do have an issue with getting ahead of the motion when jumping. I have never real jumped any other horse except for my pony (I did ride a 15.2hh gelding, but only for 2 months). As maura pointed out, my main problem is that I have a long upper body and shorter legs...plus my pony has a short neck and is a touch to small for me. I have been told this makes it harder to prevent tipping/getting ahead of your horse/pony? I am going to be riding a different horse in lessons over the winter, at a local stable, so I may be able to work on my balance more with a taller horse.
My release is my main concern, since I am not as experienced in jumping (I have more of a dressage background). I used to have almost no release, then I moved to an extreme crest release, and now that my leg is getting a bit more solid I am working on my auto realease. So it's good to hear that I am aiming in the right direction (currently I ride hunter classes, since jumper is too high for my pony, but I prefer the jumpers).
The reason my pony is dropping his leg a bit is that we actually had a really bad take off before the x-jump. :P
Thank you for all the critique!
