When will young magicians realize that reactions are not the end all to be all - reactions are an instant emotional response - and only ONE way to gain feedback. I once took cards out of my pocket, and the girl didn't see...and she screamed, "Oh my god - where did those cards come from"...her friends said,"he pulled them out and you weren't watching"...she looks, "oh" - and blushes. It is amazing what people will "react" to, but later think about and realize method. Moreover, when you are new to magic or young (even as much as 2-3 years) - you get stronger reactions for bad stuff...why? People expect very little out of you, so if you do more than nothing - reactions!? Not exactly the greatest way to measure the success of your magic - long term for certain. You have to be your own judge.
I would say this about what I saw - looking at it like a lay person - but speaking like a magician.
Your magic has not plot - just music - so when you really do it...do you turn on music? No? Well, then why did you make me sit through that song?
Next - your very first control - it look like a control - it was very precise and careful handling...it looked like you were keeping track of the card...why? Because you were. Look to have a loose handling, and practice your controls more to make it look natural.
Next to next - both times you have NO motivation to touch the cards to the deck. This is called the NO touch principle - you touch the cards to the deck..and then the card is there - I don't know how it gets there, but I know WHEN...when you touched the cards on the deck, for no reason but to steal the card. This is bad construction.
Also, when you spread the cards with your hand to make it appear between two cards...it looks like you just spread the cards...again, a tell. Oh...where was the card...hiding between those two other cards.
Will the average person get that stuff - no? However, I don't want to fool the easy ones, I want to fool them all...the real hard ones - as Swiss says, the rest come for free.
For the last phase - it looked nice on camera - I would recommend a turnover pass as you turn the deck face up and put it down - so you centre the cards, rather than cutting them at that point - which reminded me later...oh, he cut the cards to centre the top pack...as he came to the top of the deck again for no reason.
Overall, it was average - make those changes, and it could be good.
On a side, yet related note, I never did like the idea of 2 cards finding one - it make no sense.
Good luck. Hope that feedback helps.
