The colours in this image are really nice, I love how the sky has this deep blue even though the original photo was taken directly against the sun. I also love all those little details like the hands in the sun, who, without being seen at first sight add nice little messages to the overall message that is being conveyed by the image itself and especially the words/text/poem that is written on it.
I would have liked it if you had given the credit to the stock images you used, as I could look them up and give you a nice critique on how you used, as well as being able to find them myself and use them, if I wanted to.
The overall image is very nicely done, there are only minor points that I would have liked to see in a different way. Which does not mean you did them wrong.
I would have liked to see the (image) left side hand a bit smaller, as it is (probably due to photo angle) so much bigger than the right side hand.
And I would have liked it very much, if there would have been a few details on the silhouette of the man. You added the hands into the sun, I don't think it would have been too difficult to add a little detail to the man.
Especially around the points of where you added the car lights, you could have added a few details as if the lights where a second lightsource. You could have cut out the white dotted road lines to avoid people seeing this easily that the nicely coloured lines come from car photos. I would have moved the upper right white line a bit to the left, so that it looks as if it came around the arm instead of having it start somewhere behind the arm.

The vision of your image is nice, you had one and tried to convey it. The only thing I'm not sure about is how cars relate to the vision, the message. This is why I wrote you could have made it more difficult for people to see where you got the lines from. I think your vision was great, but something in the way you choose to convey it made, that parts of it got lost or maybe added without intent.
Oh, and I would have loved it, if you had rewritten the text in your artists comments as sometimes letters are getting lost on the dark background. It could have been avoided by using a grey with a low opacity instead of a blending mode.
Originality is something that is hard to come by these days, just because there always already are images with a similar theme and layout. There are hundreds of thousands silhouette picture around, but I rarely see them in this way, in their natural habitat. Therefore I'd say you found the hard to come by originality.
Technique is good, I can't really see any technical errors. I just don't like giving 5 out of 5 because there are so many ways of getting to the result.
Impact The image has a lot of impact, if you take the time to really look at it and read the words. It isn't really an image lots of people would pick out of a list of thumbnails, and I guess that could be improved, even though I'm not totally sure how.

Sorry for me taking this long
