Personally I love UStream and livestream and stuff like that. I've watched so many great artists, including my personal art IDOLS draw live, right in front of me, and even got to talk to them a little through the chat. I think everyone should do it! It's such an incredible learning experience.
And speaking of, I'll be UStreaming tomorrow night at 7pm! I'll be drawing your requests. :] Tell your friends! Free art! Watch this space for a link to the broadcast.
