Welcome from me, too, Elle.
I agree with aus*jen, not the same man.
Some of the differences can perhaps be shoved under the carpet. The thinner jaw/chin/cheeks of the older man could be due to his age. And the younger man’s right ear may be pressed against the mirror thus flattening it (I’ve cleaned it up a little to show it more clearly). And they do have similar creases in their cheeks.
But I don’t think age or the angle/lighting of the photos explains the longer looking nose and left ear of the older man.
The biggest difference to me, however, is the shape of their skulls. One is shaped like an egg, the other like an inverted pyramid. Notice in particular the top third of the older man’s head: it is MUCH broader than the younger man’s.
Hope this helps.
Cheers,
Peter
