Not camera editing this time. However there were some suspicious moments in the way you shifted your weight and in your general body language. I don't doubt this could be a very effective illusion, but you made some very subtle mistakes.
Try this: when practicing the illusion in front of a mirror, keep the knees bent like a cat in order to keep your center of gravity stationary at all times. Watch some Tai Chi and martial arts teachers and how they move. You'll note the way that they seem to glide instead of walk because of the way they keep their knees bent and flexible to so that they can move on an even, fluid keel.
