I really like this conceptually, and the sepia was a nice choice The lighting also works very well, especially keeping the bench in shadow.
The only things I can think of that could perhaps be improved, are aspects of composition... the first thing that struck me was how out of place that tree on the left seems... I realize you can't control the tree being there, but I would suggest thinking about ways to work around obstacles like that, which could involve looking at different angles, or different ways of framing things The other thing that seems a bit out of place is the bench... but for me, I would just like to see it almost against the right-hand border, so it is facing into the openness of the rest of the picture Vertically speaking though, I like the placement of everything
