Very nice! Well done curl on the tail My suggestion is to maybe raise chest on the ponies a little, and bring it closer to the neck. The ponies in the show have round(ish) chests, and the front legs go fine with where you've put it, but the more the chest on the pony, the more back you're going to have. This is done on some ponies, but they also have high arched bellies and backs (Luna, Fleur, Cadance, etc).
I really like it though. Esme has a very similiar look to Bottlecap, actually.
