HERE IT IS AT LAST!
I finally decided to create a Patreon page (which is more complicated than Tipeee, so that’s why I was a bit reluctant at first!).
The 1$ tier gives you access to at least one painting/illustration/comic as a high resolution png file per month (at the moment there’s only two of them, but I’m open to any number of requests for high resolution files of things I’ve already made!), the 3$ tier also gives you access to work-in-progress commented posts with photos (two of them at the moment), and the 8$ tier also gives you a drawing (png file) of a tiny monster thanking you personally. I also still have a Tipeee page, which has a monthly lottery (something you can't do on Patreon).
Have a nice day!
