Honestly, I don't know if it will work. If you enjoy drawing, and on camera after trying it out, it can't hurt. There is a market for it. If you keep the channel clean and child friendly, you could reach youngsters wanting to learn how to draw.

There are some people making money from teaching art on Teachable. I forget the name, but look up "Watercolour" and "Teachable" on a search engine. I just found quite a few. Is this something that would inspire you? It might take you on a different path or even multiple paths. :)

PS: people are really getting into beginner's art courses as a form of relaxation from the modern world.
