Well, after months of thinking about it, I've finally done a sculpting video. It's not at all edited, and it cuts off abruptly, but it walks through most of the process that I've been using to reproduce my original bas relief pieces.
I don't have much confidence in my ability to hurry up and be briefer, so maybe I'll just plan to do projects in 10-15 minute chunks for filming purposes. Better to have three shorter videos in a series than one looking one that cuts off randomly.
Like everything else in this process, though, it's all a matter of learning through experience. On that note, I hope that you'll try out some of these techniques and have some new experiences of your own. Enjoy!
