I like this. Many will bleat that it isn't a portrait, but it is for me. A picture like this of my late father, for example, would have been a perfect portrait of him.
The conventional approach to portraits is of course the close up head shot with the pimped eyes and grotesquely smoothed skin. Or the gnarly head shot with the grunge processing.
The conventional approach to the challenge topic ('classic portrait' and 'typically captures the face' blah blah blah) is to be constrained by it, rather than liberated by it.
Convention and blind obedience suck, don't they? Why go along, just to produce something two-dimensional and instantly forgettable? So BRAVO you, and please accept my top pick, a 10, and an Order of the Thumb.
Thank you.
Sadly, this fabulous image is in the wrong challenge. Despite its incredible power, this is too far outside the definition of portraiture for voters to relate it as such.
