I've been trying to get more realistic people for use in my renders so have been playing around with some software called Faceshop (which is a plugin for Daz Studio). After creating the model of his face in faceshop and sending it to daz studio I then edited the skin texture in photoshop before rendering. Then I did some postwork in photoshop to try and make it look slightly more realistic (I played around with the saturation, Brightness and hue of the image and used the clone brush to copy textures to other areas of the face.) I picked Vin because he doesn't have much hair and really don't have a clue about doing models of hair yet so would have ended up painting it on in Photoshop.
