I found a model who will be great for Creed, and one who will be great for Anna Lynn.
Creed doesn't look too old, but definitely experienced, and has a rugged, old west type look to him. He's handsome and looks like he could be commanding.
Anna Lynn is beautiful, with the right body type. She looks smart and possibly devious.
These models are both from 3d.sk, and I reduced the images sizes considerably before posting them here.
