I'm judging this based knowing that it's basically a gif. I like the drawing and tweening detail in the hair. I would say to animate the tail and make the spit fall faster once it leaves her mouth. Good job :).
I'm not a fan of the show by any means, but the animation lacks dynamic movement in places like the tail. The animation kinda dies from the neck down.
So is this a movie or a gif and do they now sleep standing?
Do all ponies sleep standing?
What is up with all these male ADULTS liking my little pony? As far as I remember, it was a children's show. As for this, good draw, too bad its a loop.
