This is a cool looking road and location. Well seen! Funny how the asphalt gives the viewer an impression of a grainy image, even though it isn't. You've composed this well overall. The B/W tonal range seems just a tad short of hitting both ends (true white/true black) - but it could be this lousy work monitor. :) BTW, you know that it's ok to clone out sensor dust?
Very nice B&W treatment. I like how the rocks get darker as the eye moves left to right. Great depth and the sky looks cool. Best I've seen so far~! 10
