You performed the mechanics of the trick excellently.
However, I don't personally like this trick too much - I think it's weakened by using their selection to "find their selection"; in the video, I'm talking about the Ace of Spades.
The spectator(s), I believe, become confused by this effect, as the chosen card is shown without climax or recognition, and used to find a card that they surely know is not the chosen card.
Maybe I'm not making since, I'm extremely tired and need to sleep.
I'll edit it to make it legible tomorrow; good night.
Best regards,
Ben
