Western Horsemanship Video Critique

I made these videos for an online show and I thought I would post them to get your guys input on how I can improve. I take lessons regularly but everyone sees things different so I'm always up for learning. I didn't correct my horse in these videos but I wanted to lol! He was being a little bit naughty. He is still green at this pleasure stuff. This will be our first year competing seriously. We still have some work at the lope but coming along. Well enough with that. Let me know what you guys think.

I won't critique your horse (he's very cute though) since you said you've still got a lot to work on.
As far as you...In the pleasure settle your upper body down some. Rotate your hips back. Relax your upper body. Your back is arched and you look stiff. Loosen up the shoulders and just roll them back. Sit down into the saddle more.
For horsemanship i'd just say think tall. Its going to be more formal riding wise but not so severe. You back is still very arched. Think straight and tall and keep your butt in the saddle. Your almost riding off your crotch.
You seem to be a nice rider though. Good luck!
