Can you see the face?

Taken from the second floor of the office building I was in today. Had lone worker training all day which, although useful, was a bit tedious for someone who has been lone working for over 6 years. If I can't deal with conflict and confrontation now, I never will. Teach your grandmother to suck eggs sprang to mind.

I think there is a Darth Vader type face in the picture but maybe it's just me?
