The thing that sticks out most to me, is his high head. I think you are pulling on his face too much.
To get a better result over the fences, do a couple big halfhalts with the outside rein to get him collected over the jumps :)
Okay I didnt watch more then 35 seconds of that... you definitely need a lot more work on flat, and I would probably work over lower fences for a while! Once of these days your guys just going to crash through the jump....
Dear god you pulled that first rail like 20m!!!!!!!!! Firstly don't let him through your hands, make them softer and use seat... as it appeared that you were out of the saddle more often than not- try and relax in the saddle a bit more- let him round beneath you and establish a rhythm (ie. MORE DRESSAGE!). That will stop you have to drag and balance on his mouth to get corners and slow him before the fence.try a drop or the flash on a hanovarian to stop him gaping, will give you a bit more control too if he can't escape the pressure ;).
The fact that he pulled alot of the verticals is showing that he needs balance and impulsion behind. Impulsion doesn't mean faster, I would suggest lots of grid work... a great one for him would be ' ground rail, bounce, 1s, 2s, bounce' also ... just typing as i'm thinking here.... a few canter poles before and after a low vertcal fence (2'6ish would prob be a good height for him).
I'm under the impression that the last course on the vid is a topscore or similar so I understand speed is a major factor... but was that the last course of the day? Because he was jumping much better after getting into a rythm and knowing what he's doing..
Sorry if I was a bit harsh.. or offended you but mean well ;)
Ok, firstly, I pretty much only do flat work lol. And when I do jump (only at pony club or show really.) Its schooling and grids. He does rush. Its from what his previvous instructors did, I was wanting more position critique lol.
OHH!! And in that vid the first person is me the second one is josh and the 3rd is josh. I do ! Allot! Of flat work (no actually dressage, but flat work is dressage in a nutshell)
Here is us doing flat work
I probs should ahve said that I was only the first person in the vid, cause joshs horse is nuts as a doof.
Ok, we'll do position... I think your doing to much.. sit back a bit and drop your seat bones into the saddle, you seem perched. You need to work on releases and your hands- I noticed going around corners etc your elbows were sticking out and I could see your hands out of place (at 0:30 on the vid). And your lower leg slips back over the fences .. that's all I can see from the vid.. in the pic ur leaning forward and your hands are too low - you need to close the angle in ur elbow
