This is an amazingly cool shot. I think the impact would have been ten times greater with just one shadow, but thats jst my opinion. The lighting in this is absolute amazing from the foreground to the background that looks like fog on such a beautiful surrounding. The backdrop really is a great include i the photo. The trees are so cool, did you try the shot from one side or the other like a slant on the head on perspective. The coloring is great as well as the composition. I think it would have probably scored higher with one shadow, or at least I should say I probably would have scored it higher. I read the comments other had left. Macpapas said cool jokes about the aliens, what an idea that would be. Overall you did an awesome job and great out of the box thinking for the challenge. God job!
I think the shadows on the ground (esp. the shadow of the photographer, the other one is kind of nice) somewhat distract from the nice perspective of the alley. If you could step in the shadow and take a phot with only one shadow, it would be much stronger IMO.
I get the aliens joke, but it looks like you would have had a great perspective shot if you moved up to the edge of the shade and captured the mist and rows of trees.
I think I'd prefer the people cropped out giving the perspective and forregroundlight some more impact. You obviously tried that, but the shadow of the shot taker is distracting. Perhaps if you'd put it on timer
