To some people balance/motion is crystal clear. And some don't have a clue.

The horse above is named Burkan and the horse below is named Celebes. They were trained by a creature called a "horse man." Note the ease/balance in which they are rearing.
This clown below is not a "horse man", and doesn't have a clue. Note the ears and the legs in a defensive position, which is causing the haunches to unbalance. He is driving the front end up instead of bringing it up from a solid base, into the stifle, into the hip, into the croup, into the back/ribs, into the shoulders, into the neck. Some people teach a feline to sit up in the same backward way, which is why their front feet are up high, yet their spin in curved or collapsed. YOU NEED THAT BASE TO PUSH UP THROUGH AN ANIMALS BODY, not pushed down from the head to the hip.
