No tips from me as of now, but I have some experience… for better or for worse.
I'm trying to find out where I stand with art-as-a-way-to-support-my-existence! I'm in a bit of a burnout era after trying (and failing) to use sudden Social Media nano-celebrity recognizability to achieve it through patron support and physical/digital art/zine item sales. To the point where I almost wish I'd've stayed in the part-time+freelance+personal-projects trinity thing I had going on before that. At least I was financially safe, that way.
I think supporting oneself, wholly, or partially by one's art is certainly possible, but I can't help but feel like I've personally made some sort of mistake in trying to use Social Media as my vector of doing so.
(As I go into at depth, on my website.) If I were to go for it again, I'd probably sell my art pieces, downloads, and physical goods to visitors of my website. If someone's there, they're already gracing me with much more focused attention than wanderers of the algorithm can offer.
I'd also make more use of IRL art tabling events, like art markets, art fairs, and zine fests. (Bigger tabling events like anime conventions are a bit out of my zone, as someone whose muse and creative drive are mostly in my original fictional characters.)
When art tabling IRL, you get to form a human connection to someone who's curious about your work. You also get to befriend the organizers of the event, and your fellow tabling artists… …so I hear from friends, anyway.
I should give it a go, someday.
Addendum: I feel like there's a lot of interesting smallWeb discourse (in the discussion sense, not the drama sense) over whether art should be given for free or for sale, especially online. I think in a world where everyone's needs were met, and they didn't have to live in financial fear, it'd be cool and awesome to share all my art for free with those who want to see it.
But Capitalism is rough and the Bills™ monster is constantly coming for me.
I feel like there's also a vibe of like, "get a good real job, so you can make your art with full freedom within the Negative Space within your schedule", but… I get so intimidated by time itself. I feel like, if you want to devote a lot of time to projects, they have to be

profitable

so you can afford the time to make the art instead of having to spend that time working for someone else's, or some company's: grander goals and purpose.
