Nice study mate, his concentrated look says it all, a man with a mission.

This is superb Chris, really lovely conversion.

Great job Chris, B/W works so well, I love the expression on his face.. good sharp detail too. Very well captured, Take care Mark

I like your people photos. They're very professional. You're good... take care

Great shot Chris.  It almost looks like he works for the largest employer in the world, then you realise that it's not Mumbai CST.  B&W really adds to this shot, the high vis vest would not have done anything for the portrait in colour.  Well done, good capture.
