Please Critique Me and Brickens

I had a schooling show at the barn I ride at yesterday and I just wanted to know what you think of my position and what you think of Brickens. I know I pump a lot and that I don't have the quietest seat but I'm working on it and have been improving. Plus, Brickens is SOOO BUMPY! It's so hard to keep you bum in the saddle.

INFO ON BRICKENS:
Brickens is a 10 yr old OTTB gelding. I started riding him in November and then my parents surprised me and bought him for me for Christmas. I love Brickens to death.

Here's the videos from my show...

Thanks so much.

Its hard to critique these videos because there is only one jump with a side view.

Overall you look very stiff. Try loosening up a bit and ride with the horses stride.

Congrats on your new horse and good luck in the future

I don't have time for a full critique, but you really lean in through corners with your horse, kind of like a motorcycle. Try to support him more through turns and lift hi shoulders up.

Ok thanks. If anyone else has some tips please let me know.
