Re: Patreon- most of the artists I’ve seen using Patreon successfully are digital painters- the bonuses for donating are things like getting to see WIP images, exclusive videos of works in progress, mini-tutorials, or votes on what they’d like to see an artist paint more of etc. So it’s not a massive amount of extra effort spent in order to get a handy income boost. If I had more time to pursue my digital work as well as traditional, I’d definitely jump on the bandwagon, but sadly there are only so many hours in the day…!
I’ve never actually seen traditional artists using Patreon, and I’m not sure how they’d make the system work for them. I may have to look into it a little.
As for Youtube, I do know that a lot of painters upload videos of themselves at work, whether instructive or casual, and it seems to pull in traffic/sales for them. Not for me at all, as I want to be behind the camera, not in front of it! But for some reason, a lot of people really enjoy ‘getting to know’ the person behind the art. Unfortunate if, like me, you are a very private person and want to remain fairly anonymous and let your work speak for you! Oh well.
