I think you should add one more phase as a finale, this is a concept I apply to all of my routines. I think it is necessary to have a finale for many reasons, first of all it lets the audience know the trick is over, second it catches them off guard, if they have seen you do the same thing twice in a row they will expect the same thing again only to get "psychologically punched in the face" as I like to put it.
and lastly it keeps them wanting more... you may have seen the episode of Seinfeld where George decides that every time he makes someone laugh he will leave the room so he can make a good final impression, the same concept is applied.
(it was the first example that came to my head...don't judge. lol)
