|Hi, Jim. This is on behalf of the Critique Club.
Composition: A simple shot showing a highway leading through snow-capped mountains, made superior by the choice of portrait orientation rather than landscape. As the title suggests, this is blue sky country, and your compositional choice of 2/3rds sky evokes that feeling well. To remove the highway completely (as has been suggested) would clearly take away an important element of the story being told. I would however, like to see the removal of the light coloured area to the right of the highway that distracts and pulls the eye the wrong way; and I probably would have cropped out the intersection at the very bottom.
Technical: It is a long distance shot and therefore focus is not really an issue. You seem to have captured the light quite well. Whether or not a polarizing filter would have "improved" the image is, I think, open to question.
Overall: This doesn't have any WOW factor for me, doesn't hit me in the eye as an interesting piece. However, I believe you have well captured the mood that you probably were looking for and therefore I think it should be counted a success.
