The first pic is hard to see as it is more straight on but the second pic is better :). It is a little hard to tell, as I can't see knee angle, but your irons look a hole or two long. You want to take your normal length and shorten by at least one hole before jumping. This helps your balance in two-point which leads to a couple of the other related, but correctable, position related problems.
You are jumping ahead of your horse, meaning that you are coming forward in your two point vice just closing your hip angle..this is very common :). My trainer gave me a visual that helped immensely. When you go in to two point, concentrate on pushing the horse away with your hands. This helps to bring your center of gravity back over the top of the saddle and trust me, when done right the difference is incredible in the feeling of balance and comfort in the jump. This will also help in keeping your leg in the right position.
You don't saeem to be pinching with your knee but are gripping with the back of your calf rather than the side. This is also causing your toes to turn out much further than needed. No one has a completely straight toe even in higher levels as natural human conformation is going to bring the toe out slightly. A more solid two point, closing the hip angle rather than just coming forward, will correct this almost automatically. Your leg seems to be steady in that it isn't sliding back but it is hard to see from the angle of the pic. :)
I like the crest release in the second pic much better than the first. In the first pic it looks like you didn't release at all but just came forward over your hands...earlier in the jumping session maybe or got slightly left behind? :) You can see that your elbows are all the way back to your hip. In the second pic your hands and arms came forward giving a much better release. Your eyes are up and back looks flat which is good. :). You have the basics down..now you just need to refine things to make that really pretty picture :)
