First of all the grass!!! You should not have long green grass like that!! It's just wrong! (I'm jealous, my paddocks are very brown and almost bare at present)
The main thing I see is you are pivoting on your knee. You need to hold more with your calf which will help to keep your heel down more and leg more forward.
Other than that, it doesn't look too bad (except the grass of course)
Haha this is my mate, was her first time jumping EVER on her hrose (she jsut doesnt jump) and I madddeee her, such a honest horsey
I thought she did well, all we were focusing on was the release at first, and she is now learning to sit her butt back down and lest the horse jump
I normally ride her
That's just not right. If your friend has NEVER jumped before, you DO NOT put her over that high of a jump. You have to start off gradually. What if she had fallen and gotten hurt? You have no idea how much liability issues you would be involved in. Also, sit back. Push down, you are completely out of the saddle. Put the weight in your stirrups and put your shoulders back, look up, work on that two point.
Beyond that, the first picture, the rider needs to put their weight in their heels. And push their heels down. If that's the first jump ever, its pretty good.
For the second picture, hands should not be on the side of the horse's neck. The need to be above the mane at the lower part of the main crest of the neck. The rider also seems to have a turtle back forming.
Ya what everyone else said... :P
Haha omg I almost peed myself laughing at that second picture!!! She's holding on for dear life!!! Haha that reminds me of when I sent my dressage friend over a 3 foot jump... bahaha they hang on like theres not tomorrow!!!!!! :P my poor friends, I torture them alot haha
