I'd love to help you design your character! I have a super thorough interactive design process to nail down all necessary characteristics.
Commission sheet and design process: https://toyhou.se/~forums/71.art-marketplace/91916.custom-designs-illustrations-chibis

(I'm old enough to view NSFW content, but I will not do heavy nsfw commissions)
Thanks for considering, let me know if you have any questions or need additional creepy examples, I have some more monsterous sketches in the works
