Hmm. I like how your personality comes across. The trick, a little bit less so; here are some thoughts as to why..
-You turn on your bumbling persona at about 1:30 into the video and turn it off again at around 2:30. I think that it's a great idea to go with, but if you use it, I think that it would be more convincing if you kept the persona on the entire time. For the first half of the trick, you appear reasonably articulate, ribbon spread perfectly, and speak with normal rhythms. That makes the part where you speak quickly and move jerkily kinda non-sensical. In other words, I think you play it too straight at both ends of the trick, compared to your middle bit where your actions contradict your words in a funny way, which thus takes away from the credibility a bit.
-I'd love to see you perform this to real people. Usually when I say this, it's because I don't have a hope in the world that the person could pull it off, but I actually think you can. The reason I mention this here is because it's a trick that obviously depends on a high degree of audience interaction. I think this could be genuinely funny (and admittedly, I did laugh at one or two points), and I'd like to see that effect.
-There's something about the red/black separation that bothers me. I think mostly because if your audience gets over that phase where you mix the cards, then the only conclusion they can reach is that it was a false mix - you never show the faces, you don't make any other genuine shuffles (even half genuine ones), and so forth. So there's just that one layer of deception, the semi-genuine mix. If you get over that for whatever reason, I think the reveal feels a little bit weak, personally.
I hope these thoughts help. I would actually just like to mention that though most of these comments are negative, you're one of the few people to post YouTube videos of effects whilst actually showing personality, and that's a very big positive.
tell me what you think about the shuffles
