These two photos elicit very different emotions and thoughts. The black and white to me looks like I'm looking back in time, but the color one makes me feel that I'm seeing a painting. the color one also brings out more detail - like you can't even tell there's an engineer waving out of the door, even after you know he's there. I like the level to which you pushed the tone mapping - not quite unrealistic but again makes me think of a painting...almost.
