Pensiero

Very interesting conversion.  Not only is a section highlighted by color, but it's done so by light and detail as well.  I think it works very well.  I might even further enhance that aspect by removing the color from the road strip on the right (although it's a nice balance) and by reducing the light somewhat on the building with the sign and at the end of road where it curves out of sight.

No offense Robert but to me converting colour to black and white and then making some elements colour is a bit Tacky, I think this image would have been much stronger as a Black and White with a touch more contrast.
