Lil' bit off topic but when I find a faceclaim (always drawn) I like, I do research on that face.

Like, [i]hard[/i] research.

I attempt to find out who that face is. If it's just art from an artist then it ends there but if it's an actual character, I find out who he/she is, what franchise he/she comes from, learn about the character and the franchise, etc. I even compare her/his original personality to the personality of the OC sometimes.

I don't do this all the time, just most of the time.
