Definitely an interesting juxtaposition, as you say. I like the composition a lot, I only wish the dirt road didn't appear to veer away from the city rather than towards it.
I'm not quite sure about the B/W conversion, though. I like the tonal variations that's you've preseved in the grass and trees. I think it's the sky that's throwing me off, as it seems to lack contrast. It doesn't seem right that the foreground flowers are brighter in tone than the clouds.
Thank you everyone for the comments. I would indeed have preferred the path turn toward the city. I did quick conversion from IR setting in Elements; nothing special, just liked the result.
