This picture is very nice.
Someone says that the human eye stops on the right lower corner, so this corner should be the one with the maximum content of information in a cpicture (obviously when applicable. In a landscape this is not suitable). This seems to be the case to reflect the picture, to have the dog on the right.
About the nose: well, it's out of focus and maybe it was better on focus...
The B/W conversion is very nicely done!! I like this picture!
