Hi Snoopy123, good work on getting as far as you have done with the controls. I understand that some of them are very difficult to grasp, but there are a few things I spotted that I believe you should work on.
1.
Daniel Garcia's "Ego Slip":
What I noticed in your performance was that there was somewhat of a calm pace to it all. But as soon as you move to place the "selection" in the centre, the pace in which you move is doubled or even tripled. If you were really
just placing their card in the middle, would you go lightening-fast about it? If you continue practicing and try and work out a more economical cover, you will find your Ego Slip far more convincing. All in all, with a correct right hand motion and natural cover, no matter if the move is performed at a snails pace; the control will not be flashed from the desired angle.
2.
Olivier Macia's "Wow Control":
There is absolutely no need for the tapping before the shift is made. Instead, simply hover the packet over the cards and execute the control as the cards release from the right hand. Again, much like your 'Ego Slip' there is a drastic change in pace when the shift is executed. Please do take your time, and do not feel as though you will flash at any given moment. As it stands right now, you are flashing terribly -- not in a visual sense that you can see what is happening, but rather in that your spectator will think something is happening. When that occurs, it ruins the fun for them -- they're no longer enjoying the magic but instead trying to work out what is taking place before them.
3. Charlie Miller's "
Cascade Control":
If this is identical to the Paul Chosse method of Miller's control, then I applaud you! I think you did fantastically well. However, I have a funny feeling that it is not, and seems to me like a variation of the "Wow Control" - with an added Waterfall Flourish to complete the manoeuvre. If I am wrong, please take it as a compliment.

If I am correct in thinking that, do not take so much time before positioning the deck into the Waterfall position (or even setting the right hand pack "flush" on top for that matter), as it really tips that something is happening.

The "Riffle Pass":
There is far much to say regarding any person's performance of the Pass; including my own. From unnatural hand gestures, to blatant flashing - I have yet to see a Pass that looks like what it should be; nothing but a mere squaring of the deck.
In the end, I think it boils down more to psychological aspects than to the technical side of things - although a few (such as the Pass) could use some more work. Don't let my comments discourage you, but rather help you on your way to fantastic sleight of hand.
Warm regards,
Jordan
