tighten up your throatlatch a bit - it shouldn't be able to flop around in halter at all. The shot is kind of at a weird angle, so I can't really critique his/her build.
What breed is that? (Rocky Mtn I think...please correct me if i'm not right!) In the gaited shows that I have been to, it is frowned upon to have your horse "propping" with a hind leg - they should be fully parked out with their head up looking at something (although, not like an arab ;) ) under saddle:
actually, you look pretty good. I would change 3 things - the horse's head appears to be cranked to one side; I would straighten is head out a bit. Also, be sure your hair is secured with a hairnet so you don't have little flyaways poking out under your hat :) and lastly, I would move your number down to where the top of it is in line with the middle of your shoulders so it doesn't look like your hunched over.
Sorry if that was picky....i taught saddleseat equitation for years
. Thanks for posting! We don't get too many saddleseat critiques on here :) You and your horses look great - keep up the good work!
