Here is my feedback:
I had to watch the effect three times - the first two to understand what the plot was, and the last to watch the effect once I understood it...and by that time, I understood the method. This is where the music detracts - music is only good when the effect is clear without words or fast movements.
I don't like the switch on a flourish - as it is not magical, but confusing what is what with what looks like a production of the bottom card when you flip the deck over - this wouldn't be an issue if you weren't performing a sleight at the same time...but that IS the moment, and it looks like a moment. Not strong design for the most part.
When you did the Kelly bottom placement at the start - you had to readjust your grip, and there was MUCH tension in your right hand - actually, as most of the moves are done with the right - there is great tension in those difficult and angled sleights.
Regardless, you didn't flash - I think the only problem is clarity, mixed with flipping the deck while you perform your switch.
It is eye candy - for magicians, very neat - for audiences...perhaps with words, could work for you.
Good luck - thanks for sharing.
