Karin?? OC's for lewdest lewds series (Patreon)

Hello patrons, I've made sketch of our first  OC, I gave her name Karin, kinda fits to this character, but what name would you gave her?
Also, this is only a first sketch, and since you are 5$ patrons, you can made some suggestions, what would you change about her? There is countless of options, I'm currently just lost in thoughts....like make her a demon, elf, what outfit, hair, boobs, personality....pfffffff, there is so many options xD

This first sketch is too plain, we need some depth! So what do you think? Also I want to make more characters, what should I do as next?
