a very effective illusion, my personal recommendation would have been to have it as a trick your audience could get involved in (as we both know how this works) and be a bit more interactive, funnily enough I did this trick a few months ago on my channel ( https://www.youtube.com/watch?v=fWTTuBuAbXw if you're interested, plus you might find some more stuff to do)

but a good effort dude, keep it up!
