The move looks interesting. And I'd hate to say it, but you need to polish up the move and shoot it again. And your camera is fine. I don't know what kind of camera it is, but it looks like it shoots fine to me.
In the beginning of the video, you say what to do but you 'can't do [the catch] very well'. That takes a bit of credibility away from you, on top of the viewer not really having a visual of what you're trying to show them. On top of it all, just stating that means that you need to polish up your flourish.
These things can take time, I've been working on a flourish since January of this year and it's still being worked on.
Also, the flurry of flourishes at the end. Just limit your tutorial to just the move you're trying to teach. There's no reason to display your skill. That's what individual skill-based videos are for.
You have a good thing, it's just that I'd highly encourage you to look at some tutorials on the Wire, as well as some of the Andrei Jihk tutorials (and previews) and just analyze what they do, what makes them good, what they display and what they don't display. It's all about adding whats relevant and cutting out what isn't.
I hope this isn't discouraging in any way. I just want to try and help set you up for success. I mean, you have put the effort in making your own flourish. Let your tutorial reflect that as well.
