In the bright sunshine of midday, I suppose the vehicles traveling through the tunnel were in very black shadow. I'm sure HDR brought up some shadow detail. The sky is a natural color.
Lemme guess, Hawaii??? Love textures and colors. But seriously, why title it that way? Do you think your going to get more votes or something? it's to tally irrelevant to the subject. Sorry, 5/10
Good use of the treatment to deal with the heavy shadows and bright highlights of midday sun. I find myself looking in the tunnel to see if Clark is in there.
