what should my next adoptable set be?

there are so many of you omg. thank you so much ;_; i'm getting closer and closer to my goal of being able to do art at home full time.. speaking of which, it's time to do another adoptable batch! i already did goats and bugs, what would you like to see next? i'll make a poll w the suggestions after a few days, then i'll try to have them out in march

apart from species, i could also do what i used to do, which is working based on color palette or theme with a variety of species. i do like doing the single-category ones, though!
