For a start that link doesn't work. If you want to use the video code, you've got to take the url that comes AFTER the v=. Eg: the code should look like: [yt]AvirPSNtNKs[/yt] which comes out as:
(An example video, has no relevance to anything, ok?)
Secondly, this isn't really the place to show off your youtube channel. If you want to show us your artistic skills, pictures go down a lot better. If you want to show us your process, it's best to have some pictures of finished pieces to go with it, and not just simply a youtube video of one piece.
But hey, I'm all for seeing a new artistic style if you've got a few to show pictures of. Just remember, you need three finished pieces at least of a gallery. Perhaps take a look at the rules before you post?
