Nice got original to see the Autumn colors? since you mentioned you took it during the Autumn.
Never been there, hoping to take a trip there too... was wondering if you tried composing the shot with more of the background buildings (the domed buildings behind in "white" to have a more sense of depth?
i think it's a wonderful shot evoking emotions. it's really good. the man walking alone was alluding to the irony of no man is an island and to juxtapose that there are two lonely men in the picture.
might just be me, i don't know.
I feel that you could have used the concept of leading lines more, to your advantage in this shot. By shifting more to your left, perhaps you could have included the view or at least part of it at the end of the flight of steps... my 2 cents.
