If you want honest criticism, I will tell you this:
~The angle on the multiple stack behind the ace of hearts at the beginning was evident, and would have been much more evident in person. This puts the effect in the most jeopardy, since an obvious multiple completely un-inspires the audience. A friend of mine has a bad habit of paying little attention to viewing angles, and people always approach me to tell me that they saw the secret, but they didn't want to embarrass him. As a solution, I would recommend making sure that the angle is safe (e.g. have them directly above the cards) because any angle that is not dead-on toward the face of the card will give away the stack. The trouble with this solution is that it obviously conflicts with your ending, which is my second point.
~The vanish used at the end in combination with the Gambler's Cop could pose a risk with any angle other than that used in the video. If you do use the video angle, however, the first point still applies, and the effect is ruined. For that reason, I'd say that you might find it easier to work with a vanish using Tenkai palm under the guise of transferring the card from one hand into a "palm" position in the other hand. By no means is it necessary if you can use your own vanish at various angles.
However, if you have any interest, here it is: Begin with the card between the first and second finger of the left hand (index and middle fingers, that is) with the back of the hand toward the audience. Approach with the right hand, its back toward the audience, with the fingers of each hand pointing toward each other. As the right hand comes in front of the card that is held between the left hand's fingers, turn your entire body to the right, in the same action moving the card into left hand Tenkai palm under cover of the right hand. As this occurs, the right hand mimics gripping ("palming") the card. Bring the right hand toward your face as the left hand relaxes and rests on the edge of the table, ditching the card. Justify directing your attention to the right hand so that the audience does the same (perhaps carefully watching as the card "turns invisible"). Now the card has been lapped, and the routine is ready to come to a close with the laying down of the final invisible card.
I have used this specific vanish quite a few times, and in most situations (assuming you are seated) I have found it satisfactory. I assume that you intend only to do the routine whilst seated, so this should work for you.
~The laying down of the invisible cards, making them appear was nice but not as magical as it probably could be. Ideally, you could put your hand down without sliding it, and make the card simply appear underneath it. Moisture on the hand in combination with pressure can do a great deal to aid in making the appearance of the cards more ideal, if you are inspired to work with such an idea.
Your performance of this routine is certainly within the uppermost quartile of those that I've seen, so I hope that this critique doesn't discourage you. That isn't my intention, nor is it to speak as if I know everything (I know precious few things). I cannot perform this routine, and I don't intend to do so. However, I have seen great card magic, I have seen awful card magic, and I have seen audiences that don't have the heart to tell magicians that they have discovered their secrets. I simply hope that I can promote the former and prevent the latter.
