If you’re willing to draw furry art, there’s always a really steady demand for commissions. Doesn’t even have to be NSFW or anything, if you can draw anthropomorphic animal characters you’re all set. You’d get a fairly consistent stream of offers (depending on your ability and clout) and to me at least it’s way more profitable than trying to compete with 180000 other artists on instagram trying to sell pictures of trees.

Obviously it makes most people uncomfortable, but if you’re willing and capable it’s by far the quickest and easiest route to profitability
