Right here are some comments from my point of few, you can either take them on board, or completely ignore them. But, if you completely ignore everyone's comments, then you will never improve.
1. It dragged out a bit long, we seemed to be waiting for quite a while, it maybe for suspense, but it was a bit too long I feel.
2. Where is your audience? - This would look more professional, and more entertaining if there was an audience. Even if you set up a couple of chairs in the park, or get people standing there watching you. Surely you have friends and family who would watch.
3. I wouldn't put 'Copyright 2009' on the video, because you cannot copy someone else's material (such as the voice at the start, and the recorded video which was not owned by yourself).
4. Lose some of the editing, some of it was way too much to actually see what was going on. If all the editing is going on too, it gives the viewers to think that if you can do all that editing, what if he could edit the magic? - It loses the touch of real magic.
5. Please can you explain to me how you are a magic consultant? - Not to be harsh, but, you do not seem ready to actually consult other magicians.
6. Anyway, keep it up.
If I think of more, I shall say.
