They didn't give credit for the tutorial so I guess its copyrightHmm, I'm trying to figure out whether that would be copyright. As technically it's just a step-by-step drawing video and not someone's individual unique artwork that they've simply put on display for others to look at and not copy. The main purpose of that video is to copy her drawing.
Not defending them, I don't support anything of what they do, but I can't help but to state that.
