The quality of the camera is okay, it's the slots that I'm having issues with. It doesn't work well with what you are trying to do. I'd use a wide shot at the least.
Locations! As said, magic in the bed room for essentially the camera (though the camera dude did hold a card or so) is boring. Youtube magic seldom works because you don't have any clue if or how you connect with your audience. This would be way better if done for actual spectators at your local mall or school... unless the point of this is rehearsal. If this is a rehearsal video to just review your moves/ patter then that's all together different. It works for that. Just don't go making this a public link, and take it down after you get what you are looking for. This, as a performance, is not ready to be seen by the general public.
Wardrobe. You're wardrobe selection sucks for performing. You need to look better. No shorts, slacks, and a polo shirt for business casual. Or Khakis. Honestly, I'd like to see you develop your personal character more, but that's probably getting the cart before the horse. Right now, just dress sharper. And for god sakes man put some damn shoes on! Again, this point is moot if you're just doing this as a rehearsal vid. Then it doesn't matter what you are wearing.
Presentation: Are you running off of a script? Doesn't sound like it. Fix that, script everything.
Sound: You're using Penn & Teller's BS entrance music, and looping it. if you're going to loop the same piece of music over and over, take the volume down 50% so it's just audible enough to register, but not annoy with redundancy. Otherwise, I'd select different music per segment or a longer track.
Entertain me! For what it is your video is about four minutes too long to be entertaining. It's just a series of card tricks, following card tricks with very little motivation (other than look at what I can do), or reason for me to invest myself into who you are and why you're doing this. As an adult watching a magic set I'll be more than glad to waste three minutes of my time to watch you stumble through one effect, but if you want me to engage you for more than that (even up to the seven minutes your video runs) then you had better be entertaining!
Here's the rough part, no one can teach you how to be entertaining. So far, from what I've seen, it's something either you do, or don't do. Presentation, scripting, timing, and humor will help you a lot though. You need to get me interested in who you are, and what you are doing. Watch others perform the tricks that you are doing, and watch HOW they do it. Forget the technicalities, that doesn't matter. Watch their body language, dialog delivery, pauses, speech, tone of voice, inflections on the voice, jokes, patter, etc. Learn to emulate, before you create.
Your double lifts aren't horribly slick, but they are workable. They look like you're doing something magical, but your average layman won't know what it is you are doing- only that you are doing something. Which can be argued as being just as bad. I'd review your double lift material, and try to refine it a little more. Shouldn't take much effort though, you're mostly there as it is.
It's a work in progress, and you are making progress! There is a lot of room to improve upon, but that isn't a bad thing. We all have reason to improve. No one is perfect so keep it up.
