From a purely technical point of view, I'd say that your closeup is good. The depth of field that you chose to use shows up the two features in the front very well with no distracting blurred bits in the foreground, which in my experience, is not the easiest thing to do. So that leaves the background pleasantly blurred.

very good and interesting shot!

I like this, Mauntnbeika.

Going in, I'll say this about me -- I have a bent for the macro because it explains the elements of being to me, and I love b&w because it cancels out my color addiction. Given those innate plusses, this is a fascinating pic because it takes us where we don't ordinarily go and gives us a nose-to-reality understanding of something very basic: where do roads come from and how do we make things?

All "conceptual" aside, I like the use of depth of field to define the area of interest (the thingy at the 1/3rd from the left "sweet spot" and it's friend at the far right), while still conveying the larger context moving off into perpetuity. Good gray-tone range. Good use of available (?) -- or anyway, subtle -- light.

Nothing's what's expected here.

All is skillfully controlled.

Brave choice of subjects.

Double kisses.

Do more!
