At 0:35, you clearly turn the king so that it should be facing the camera, but the card that you pull out has the back toward the camera. This is a discrepancy that'll be fairly obvious, even to eyes of laymen. Your wrist kill there is also jerky as well, and draws too much attention. It doesn't feel justified, and makes it seem like you're hiding something. If the spectator suspects that the card might not be the king, especially if they notice that it's facing the wrong way, the entire illusion unravels.
For a reversal plot, I prefer Inversion and the Biddle Trick. The handling is much more clean throughout than what you have here, and the presentation provides more natural misdirection at the right moments.
EDIT: That said, with the right patter and connection to your spectator, you can get away with all kinds of things. If you like this plot, the main thing I'd suggest from what I saw is smoothing over that discrepancy. You'll probably want to adjust the handling there.
