October is kinda spoiled for choice! 🤣 Birdtober is probably the most popular, if you want/need something where there are more other people participating. Paleoctober is probably next, and I think Epochtober is new this year (at least, first year I've seen it).

Really like the idea of a Birdtober, as I tend to draw mostly birds (and forced me to avoid any bird sketch during the SciartSeptember). Nevertheless, the prompts are very species specific, and I would prefer more local ones. Maybe changing or making similar ones?
