Very graphic in terms of line and shape. Nice wide range of tones. There's too much foreground IMHO. Perhaps crop out just enough so that you end up with a square format. Looks like the edge of the world.
I like very much this image, the contrast between black vulcanic rocks ant the sky and white clouds, the road cutting through the image, the off center car, everything catch my eye; but IMO the square 6x6 framing is not the best here, I would crop some of the bottom or top to get a rectangular, less static composition; great pic anyway! regards - marco
