How Do I Do Better With My Art?

What most people want in an art channel is to see you drawing it. I'm going to be blunt here - it's hard for people to pay attention for a long video like yours staring at the same picture while you talk. What I would suggest, which would make them a lot more interesting and give you a better chance of people watching to the end, is to film yourself drawing it. That will probably take a while, so then edit it and speed it up a bit, probably don't want to go too far over 15 mins maximum but that will depend on how much you have to say over it. Then record yourself talking about what you want to talk about and put it onto the video, that way people get to watch you draw it (looking at the finished product for several minutes kind of defeats the point of it being a video) and to hear what you have to say. So I think that would make the videos more enjoyable and interesting :)
