Thanks so much, y'all! :) I love reading/researching up things on horses, so I'll try to do more of that.
My main issue at the moment is progressing my riding (developing more of an independent seat, and transitioning from a walk, trot, canter, etc) plus I'd like having more of a relationship/connection with my mare. I'm able to ride her every day, if not every other day, and that helps me tons.
I suppose that what I really lack is just experience in general, so I probably should just keep doing what I'm doing, and continue research more, until I can find a good trainer to help me out. But y'all's suggestions are really helpful. I think I have the 40 fundamentals of English riding, I need to go find it and read it, it'll probably help me out a lot.
