Velvet did a good job telling you about each picture, so I'll go a little more general... For some reason, you seem a little stiff to me. I'm not sure what it is about your posture, but you just don't seem totally comfortable. (That's not to say you're a bad rider or anything. Just how it seems. Which would also make sense if you haven't been able to jump a lot lately.) Anyway, I'm going to go out on a limb here and take a guess... When you land your jumps, do you round your shoulders? Like, when the horse is landing are you sitting up too quickly and absorbing the horse's movement in your shoulders and upper back? (If that doesn't make any sense, let me know and I'll dig up a picture.)
You seem to "tip" more than you go into two point. Rather than keeping your leg under you and your hips back over the saddle, your whole body is rocking forward and you're jumping ahead a little. Your toes are also pointed out too much, which is causing your knee to rotate out, especially on the landings. I've also found from personal experience, that when your toes are too far out it causes you to jump ahead. Try working in 2 point on the flat to help keep your toes in. It takes awhile to fix, but once you do it makes a huge difference :)
Your release is okay, but I feel like you won't adjust it much as the jumps get bigger. Your horse really uses his head when he jumps, so as the jumps get larger you need to make sure you give him his head so he can fully use himself. I wouldn't work on an auto release until you can balance yourself a little better, but with a little bit of work on that I think you could definitely be a phenomenal rider. Overall you're a nice, relaxed rider. There's a few things you can work on but nothing major :)
Nowwww, your horse. I don't have much to say about him, but he's CUTE! He looks like he's a great jumper, but you're right, he definitely isn't very interested in these little jumps ;) I think when they get bigger he'll snap his knees up more. Seems like he has quite a bit of jump to him too. I noticed he took a short spot on a lot of these jumps... It may just be these pictures, but if he does that a lot you might want to work on striding a little better so the jumps are smoother and he can round over them easier.
Hopefully I didn't come across as too harsh in any of that; if I did I didn't mean to. It's also just my personal opinion. I'm sure there's people who'll disagree with me on some of my points... You guys look really good together and I think you make an awesome pair.
