I quiet liked it. But I agree with the others: beginning could be changed for something with the still background. And I also think, it would be nice to see some magic in action, as it's your promo
I would have to disagree on that point. It seems as if spectators reactions to the magic typically sells better than the magic itself. The potential client wants to feel as the people in the video do, therefore they hire you.
Besides, showing your magic in a promo is kinda like spoiling the end to a movie. You only want to show just enough to make your audience curious and not give away any plots or conclusions. But I'd have to agree, your audience reaction is ten times more important.
I somewhat disagree. I had a laymen come up to me and tell me my video doesnt show anything and just shows people reacting.
