I see companionship - whoever sits on that chair each day, so level as it is with the window, must do to converse with someone on the other side of the window. The chair stands as welcoming concession to a regular visitor. That's what I'd like to imagine about it.
a simple and familiar composition, but in a strange and unfamiliar world. Your processing only helps the unfamiliarity. The window? next to the door looks more like the scar of a half-forgotten door. The chair is being sucked into it. The sparse details are exquisite: The flowers on the chair, the grooves in the door. The stony textures on every plane flatten this picture out. The "sculpting" shadows do create a 3-D effect, but it doesn't quite match a sense of fully realized 3-dimensional space.
This is the kind of shot that makes me want to know more, like why the chair is there, and why that chair with its spindly little legs next to the massively solid stones of the wall and street. There is a story here and I'm left to imagine it.
