ok ur trademark is definitely ur icon as no matter how many times u change it or what u change it to - it's always the same blue haired girl (idk who she is tho rip 😅) but i see her and it's like 'oh! that's that user again!'
character wise ur trademark is how a decent chunk of ur characters are all these cute, small, fantasy looking creatures (like nef and kana)! i've never seen anything quite like them in the year+ i've been on this site and they're all really unique :D
