sorry, but I don't see that this meets the challenge. I don't see a subject. If you had a car comeing around the corner then it would meet the challenge.
The line doesn't enhance the picture much. Now if it was a sweeping S curve, with leading straight down to the bottom of the picture that would be much better.
interesting landscape shot... the road leads my eye through the scene... it doesn't end up on a subject, but maybe the road is the subject... - setzler
