A nice experiment that doesn't really work as you on the right is blurred and you on the left appears to have a crease running down your face! There is also some marks in the top left of image (Cannot make it out due to low resolution of monitor).
Without the title I don't think I would have caught on that both these images were of yourself. As a photo it has potential although I don't think you quite caught it here. There is a line of shadow running vertically down the face of you in the tie and you in the sweater are far too fuzzy and unfocused. To make a more obvious point about proportion you should have made sure your shirt and tie were much neater. At any rate, I think this is stretching the idea of proportion a bit. Sure there is contrast between a working stiff and a casual guy in a sweater but I don't think that really illustrates proportion or lack of proportion.
