Fahim,
When I see a beard with such clothes, I immediately think of a devout man, concerned with meditation or prayer and not a laborer. Of course, even laborers can be devout and everyone, not on a happy income, has to get some job to put bread on the table, but it's not like a workman here in my area, where the clothes might be more rigged, rough and even shabby.
Also his left hand is held low which to me indicates that he might not be used to using the pick-axe.
I wonder what he's trying to do.
