I had a compilation album to do and it involved about six bands, and I didn't want to do the same old bandy type posed shots. So I took headshots of everyone, and for each band got an unusual facial feature from every member and used it as a composite. For the front cover I used a blend of everyone's face. (top left image) It's amazing how attractive the average of all the faces looks compared to the composites.
Mother nature did a pretty good job before I starting messing it up.
