Awoobis on patreon had this idea, see.

I offer priority sketch slots to special supporters on patreon until the Star benefit tier. Awoobis is using theirs to fuel a growth drive of sorts. If you'd like to contribute to this drive, please donate via kofi https://ko-fi.com/dlesang . It's going to be my primary way of keeping track of donations for this drive. Please include the keyword "blackcat" in your comment so i know you're donating specifically for this drive and can count it.

if you'd like to pledge to my patreon, here's a link. https://www.patreon.com/dlesang Star tier benefits are currently all taken, tho.
