For me, the B&W treatment does not work, at least not on this contrast level. For me, Tuscany is all about gently rolling hills, misty mornings, soft light and pastel colors, none of which (aside from the hills) appears to be captured here.
The inclusion of the hand of man (the stop sign, letters on the road) further ruins the image for me (sorry, Russ). It just kills the timelessness that I associate with images of Tuscany. Yes, I am aware that the road itself is another "hand of man", yet, without those obvious signs of modernity, it could have been a dirt road from a bygone era just as well.
Compositionally, the inclusion of the road parallel to the bottom of the image breaks the gentle s-curve that so nicely leads the eye through the image.
I am a great fan of your photography, by the way, so I hope that this critique will be perceived as helpful.
