Well if you want it to look more like her left hoof is facing the other way, flip the shoe around so the top of the shoe is on the ground. For the shoes you need to consider what the pony would look like standing up, and this design would be terribly uncomfortable. The shoe would more likely just go around the hoof and not up to the joint, like you have on the back hooves. That's just my opinion, though, you do what you want!
