From the compositional point of view, I like it more when I view it with the browser rather than the imageviewer.
Let me explain: with the browser I see the photo "cropped" slightly before the end of the right tree.
I noticed that this "crop" gives me a sense of "story in the making", while the full shot with the complete right tree and the empty space after it gives me a sense of a story with nothing else to be told.
About the black&white conversion, I like it but, for my personal taste, I prefer the sky more "black and contrasted" and the highlight in the foreground more "highlight".
But, for this, must be kept in mind that I'm viewing the photo on a 5 years old 40$ lcd display.
