I technically am sort of writing a "sister series" which shares the same lore and a few characters. Tho I would not call it a sequel because I sort to also want them to stand alone.
I did have more planned for Sugar Land and I guess if that series hit 1k followers or something, I might be open to adding on to it. I don't really have much motivation to really return to that series at this moment.
For Crow's Worth, I was brainstorming maybe having some extra series that I could add smaller bit to. Be it a gag-a-day style comic or a webnovel with short stories. Tho success won't be the thing motivating me to do those things, I just like making stuff with my characters.
