What kind of characters would you like? centaurs? Furry? Pokemon? Monsters? Japanese theme? maybe there are some ideas for ychs that you would like? I'm running out of ideas

Unless you have arachnophobia, you could use some cool funky kinds of spiders(like mirror spiders and Florida crab spider for examples). Or just lesser known animals in general (mother nature loves making cool funky little fellas that can be used to make some neat character designs)
