I don't usually comment on these things, but I do think colour would have made all the difference, and in a positive way.
I never thought of Tuscany as being so harsh - all the pics I associate with it are indeed misty, but rolling green hills, furrowed farmland and strategically placed Van Gogh trees dodging winding roads...
That's what you get for daring to be different!
I have to agree. looking over them you see something missing. Even as mentioned the composition framing is a bit 1 dimentional, but the images look like they have something to say, but can't say it (if that makes sense)...and perhaps most importantly with "Tuscany" as the theme, its the color. Regarding composition, the second 2 are strongest.
....Mind you I am a BW lover
