I've concluded that these sort of 3D likenesses are so tenuous that they only really work from particular angles. So with Adam's @D0gg0d and my pictures with low camera angles it's hard to see the likeness. This one is in profile and I think it works a little better.
Good point, really. Once you see it from angles that are not directly head-on or side-view, it does get harder to make the connection... in this case, the side view does it rather well.
