I do something similar when it comes to creating my characters. I like to form a clear mental picture that I can return to, something that helps me stay connected to who they are as I write. That’s really the reason I do it. I hadn’t thought about sharing images the way you did, though. I tend to keep mine private, almost like a little secret between me and the character.

I really like this image of Sebastian. It fits him well.

Kind wishes,
