I am no cups and balls guru, but the only advice I would give is to vary your vanishes. Do somthing else to make it less of a "routine". It was really well done other than that. I am afraid instead of enjoying I was watching for every move, and expecting so I can't critique fairly on that aspect. Just switch her up a bit to make it less repetative.
Keep the progress coming too, the more you add to it or if you refilm I would love to see. I like cups and balls alot, I have never bought a set though
