I find the pose brilliant on a photo I would want to see.
The face of the old man just HAVE to be captured on "film".
Indeed well done.
Some critique if I may..
The black structure above the man's head is distracting.
A featureless wall above him would be great -- cloned fill perhaps?
The background bench on left bothers me only a bit.
Is the pole (top to bottom) curved because of the lens distortion or am I deceived by the small image?
If I am right, you can consider "bending" the pole straight.
All this is minor however to a great photo. So good of you to share it with us.
