I like the visual treatment, but somehow it fails to be moody enough. Maybe it's the composition or maybe it would work better if it was not so sharp... I would try softening the whole image to create more mood. This of course might be just a personal preference but it's the way I feel when I look at the image.
A somewhat ordinary looking shot, marred by the blown highlights on the leaves. For a shot where you're going to convert to black and white anyway, you might try underexposing slightly, then dropping contrast and shadow values.
Great exposure. The only criticism I can come up with is to point out the small intrusion in the lower right corner (crack in the pavement?) Perhaps this could be cropped off. There's a real sense of atmosphere here.
