Here's the thing, the Mic just ruined it. Hell if you have mic problems, why not just go the safe route and use subtitles? I know youtube has them now and they are easy as pie to use.
You handling was just awkward and rushed. The fact that you are a "stage magician" has nothing to with it. Even if it did, most Stage magicians would have put up the video with a good mic (they're about 20-30 bucks tops at your local Office Max or Best Buy.).
Here's the other thing, If you learned that 4 years ago, it wouldn't have sucked. The handling would have been actually good to half way decent.
I still question WHERE you learned it from. Because it seemed like you learned it from a youtube guy, who also learned it from a youtube guy, etc etc. See where this is going?
I do think you need to stop performing for youtube and start performing for real people.
