I'd like to see a bit more contrast in this shot, the guys face looks full of character and I think a curves adjustment could have made more use of this.
I think if you would have off-set the man (not centered him), the overall imagery would have greatly improved and would have made me score your photo a 10 rather then what I hope is a respectable 8.
This is one of my favorite shots in this challenge. It meets the challenge in a less obvious way which is refreshing. The tones and color cast are both lovely! I bet this gentleman has interesting stories to tell.
It's a pity you cut his foot off. The central composition doesn't work for me. Maybe you could have got him further up the track and included a bit more of a hint of the bend in the road. Also it could be a bit sharper.
