I noticed some peoples comments about taking you knee off the saddle. What I think you should have even contact through out your whole leg, thigh, knee, and calf. You are putting too much pressure on your knee. When you are going over a jump try and stick your legs out in front of you and sink your heals down, that should help you distribute even contact through your whole leg. Your leg should look similar to this picture when you are in the air jumping Screen shot 2011-10-18 at 8.45.23 PM | Flickr - Photo Sharing!
I'm Ok with your crest release, but try not to get too forward, your butt should stay hovered over the saddle for the entire jump...some pictures you are jumping ahead and ducking onto the horses neck, and your leg slips back.
Practicing your 2-point on the flat should help with all of this.
Other then that, I think you look like a very strong rider. Your position is good otherwise.
You have a very beautiful horse, except he jumps a little flat.. He almost has it, but he seems like he is being restricted from using his back.
