I think you are rushing everything too much. Your making videos of these sleights after a few minutes of practice and you even type that in onto youtube. Spend several minutes/hours a day practicing it until you can get everything so that it seems natural! Don't just post up videos after 10 minutes of practice.
I'm not trying to bash you or anything but clearly you need more work on practicing to make everything smoother and more fluid. I tell you this because I've made the same mistakes before.
There's nothing wrong with your technique on the Ego change. I don't know the in your face change so I won't comment. I would be nice if you would show the DL before the Ego Change. Try to make the regripping of the deck for the Ego Change more subtle.
Here's a performance of the Ego Change I did a while ago now. Hopefully it'll help you.
