Overall, mediocre.
Here's what, why, and how you can change it:
1) The shaking of the deck: it really looks like you're stabbing someone with an invisible knife when you shake the deck. Now, this wouldn't be as big of an issue if it didn't clash as much with everything that you were doing. Watch your performance again, what you have are these slow, deliberate movements, and then you go into baby shaking with the cards.
2) Timing and grace: take a look from 0:03 to about 0:08. as a magician, I can tell you exactly what you're doing. As a spectator I'm wondering what the f**k you're doing and why its taking what seems like like an hour. And, then, quite anticlimactically, I am shown a card. If you're very lucky, your audience'll let that slide. Now, fast forward to about 2:18 and watch till about 3:17. By the time you got that card under the top (second position), I had blown out the candles for my 70th. What made it worse was that half the time, it looked like the card hadn't moved at all.
3) Oiling the gears: Here are a few things that I recommend you work on, you seem to know what to do, but execution is where you fall short.
A) Taking singles as opposed to doubles. Ideally, they should look the same.
B) Keep the control, but at a commonplace speed. You don't need to be so slow and deliberate that it's painful or worse, confusing.
C) Keep your breaks "unbroken" in the front. If this is not yet attainable, turn your body while simultaneously performing the sleight, as it is harder to focus in on a moving target.
4) And a pet peeve I have: I'm confident that you love music and want to share it with others via your magic videos; however, we need to be able to hear what youre saying. there are very few effects which accommodate silence, I must inform you that your ACR routine is not one of them. Also, subtitles don't replace you thinking on your feet, nor do they appear in real life. If your camera does not record sound, disregard this paragraph.
All in all, you were mediocre. I'm not trying to be a douche, just firm in my advice. from experience, I can tell you that going anywhere thinking that a 6 second "ready, set, go" DL works, simply wont fly. If you have any questions, please feel free to PM me, I would be happy to help.
