...Anytime you post a critique you are going to get it from all angles... it's just the way the game plays out...Trust me... I know...
As for the horse, it's a cute little mover although to me, it looks more english then western. I think you can slow her down once you start with collection but to me, she looks like an english mover.
Her neck is a little thin and could use muscling but that will come with collection, to me right now it looks like you are mainly concerned with forward movement. Collection will clean up your picture so once you get to that portion of your training you'll have to post another video!
How long has she been under saddle? She looks very sweet and willing...
"Be a best friend, tell the truth, and overuse I love you
Go to work, do your best, don't outsmart your common sense
Never let your prayin knees get lazy
And love like crazy"
