I like the magic tunnel. The control looks super natural and I doubt any layman would be able to work it out since its very well covered and smoothly done.
I love the erdnase change. You do it very smoothly. I hate it when you can see the top card being OBVIOUSLY pushed forward. Many people do it like that as if its ok, but I think hiding/covering that part of the setup makes the change so much smoother and more deceptive. Maybe you could minimise the waving just a little which would make the final change a bit more "open", instant and visible? Although in saying that, the slow, multiple wave you do has it's place and is still very magical
The card control was my least favourite of the 3, but still very impressive. I pick it out though because although I don't think I've heard of the control before I could work it out instantly. Just a bit more subtlety on the replacement I think would help fix this.
Keep up the great work dude. I hope you are proud of yourself; this is great stuff!
