This was very cleverly done! I think you could make use of this trick again with another theme--this time including all of the saw blade and chosing your setting very carefully, e.g., in front of a landscape or other "lines and shapes" type settings would make a very cool "geometric abstract". Or even a social commentary, in front of something you think should be "sawed"!
I think the background prevents this shot from been a ribbon contender. Perhaps a good example where the background makes or breaks the photo. Good luck
