It may be that you won't agree with me, but in my mind "candid" implies a photograph of a person at a candid (i.e. unaware of the camera) moment. So, to that way of thinking, this doesn't really meet the challenge. I suppose you're breaking new ground ... a candid photo of a landscape.
This is a landscape photograph. Even the presence of the trucks in the far reaches cannot in anyway bring a connotation of candid to me. Photgraphically, the image has a nice leading line of the highway, the horizon is split along the bottom 3rd nicely and it is well exposed for the capture that you have taken. There is an abundance of noise in the sky and hills that should be eliminated with Noise Ninja or Neat Image, but the subject overall has little to bring me back to wanting to view it again. Combined, lack of challenge validity, excessive noise, and minimal artistic value or interest level: apologies for a 1.
I bet you are getting hammered as bad as I am :)
I like the shot but I think it could use some additional adjustments with curves and etc. I may have cropped out the poles also. Nice idea.
