It comes down to ROI. How much energy are you investing to earn the £100? I'd rather put the time towards profitable ventures. Clicking through emails, taking surveys, and joining things is fine if you want to do it. But I'd focus on the main thing first.
Getting the site up and selling art is a bigger priority. Turn them into digital prints and coloring pages for scale. Now you're talking. Post them on them on Instagram with a link to your site. Share your process and inspiration. Monetize it with links to materials, books, etc. Create a course on unleashing your inner artist, drawing, painting, etc.
If I wanted to be a painter. My pieces are the top of the food chain. The next rung is a retreat. Then a workshop. Then a digital summit. Then a course. Then a digital print. Then a printable (coloring pages, etc.). That's my funnel. It expands your platform and provides an entry point for the audience. You're capitalizing on both mediums.
That provides multiple income streams + visibility (summit) + ad revenue (if desired) + affiliate income. You can do sponsored posts as well.
When you make your name you can explore licensing. Or do it on your own terms as demonstrated. Or do both. Thomas Kinkade is a good example. I read his story, Billion Dollar Painter. The man was gifted.
ETA: Once you have your framework you can do the same for other ventures. Books, travel, etc. You could monetize your life if you're smart.
If you recall my comments on lifestyle design, that remark should unleash a grenade in your head. I built a life around my purpose.
I’m pretty sure I got a twitter account originally to get swagbucks. I had to use Google for any queries I had that weren’t toward known sites though because the search engine seemed lacking at the time.
