I like it a lot. Well done. I can find only 2 things to critique and they are both minor. First, the sign in the lower right is very jarring, given the overall serenety of the rest of the shot - clone or crop, your choice. Same with the smokestacks (?) Second, I would selectivly rotate the horizon on the lower left just a weeeeeee bit clockwise.
Very nice, I would be proud.
PS - also, I am not sure about the point of the roof actually touching the edge. I did not mention it at first as it looked deliberate and a compositional focus. Then I got to thinking about the actual mechanics of framing this, and you would lose the point behind the mat anyways. Just something to think about.
