i bought this character from wyruil on instagram, however they have since deleted that account. i believe they are goldiilockz on deviantart.
this was the ref sheet wyruil made of her before selling her. i didnt think to ask them at the time, but i think they purchased the design from someone else too- this girls been around it seems lol
EDIT: with some friends help, and plenty of digging around through old instagram posts, chasing links, ive found her original designer!
she was designed by rokirokinorooru on deviantart. wyruil acquired the design, then sold her to me. very happy to know her roots now
