how do i do face claims for video games/animated stuff?

(i posted this somewhere else but i didn’t get any responses so im hoping to get some here)

i’m making a life is strange script for post reunion and i’m at the face claim making part, i can’t draw, i don’t have any money to commission someone, i don’t wanna use ai and i have no idea how else i would make it. i don’t want to just use a pic off pinterest i want it to look like it could be from the game so i can imagine it better if ykwim, i know i don’t need a script or face claim but i like to have both because im not good at visualizing or describing what i want so i need a photo or whatever to look at before i shift, it’d be great if i could get some advice thanks!
