The third is a simulation of a cheap digital camera flash shot, the one's with the flash to the left of the lens. IMO, the shadow's are exactly what one would expect within that criteria.
Personally, I think the "out-of-the-box" thinking that went into painstakingly recreating (with CG) a cheesy amateurish look deserves acknowledgment, or at least a smile (which, ironically, is what is unrealistic about the all three images, lips tightly shut).
Of course, far too many cg images have figures with all the facial expression of Robert Palmer's girl band.
