I'm going through the entries, stopping at those images I feel have had the benefit of an unconventional eye and dwelling a little longer to try to see and appreciate what you saw. This is one of those images.
Positives: Wonderfully Beautifully subtle portrait (from memory, this looks like Clive's dad). The dark side of the face is sublime - exactly the right amount of luminosity; and the DOF works so well. the slightly eccentric framing and the use of negative space works (but not without some slight discordant visual harmonic) - you've create some visual tension there.
Critical stuff: Despite the above, my brain wants me to say that it wants a bit more room below his chin.
Overall: Masterfully done - portrait over picture. Well done.
