^ I appreciate the feedback, thanks.
Yeah, I usually try to match up the orientation of the eyes and mouth, attempting to scale until they're about the same. But sometimes that doesn't work due to different proportions for each person, or the camera angle. I did shrink his head just a touch and I think it looks a little better. The real key is finding images with the same light source position and shadow casting. I imagine a professional can mimic light sources and shadows, but I've not had much luck with trying it. Anyway, it's fun to come up with passable looking scenes that never happened.
