I like the open mouths on both of them and the colors are wonderful. Can't help wishing the dog's head was not cut off though I'm sure others will find that fact the charm of the photo. Voted earlier.
Great photo but going with the Cinematic bars and losing the dogs face IMHO was not helpful. still an 8 but to be honest, I think in a taller crop I would have put this as top billing
Even though the dog's head has been cropped off I find this image highly appealing...and it is because of the great expressions of both boy and dog. I see the boy's mouth as hanging down in astonishment while the dog's mouth is happily panting away with that great big tongue hanging out. The colors, composition of elements and details are just great in this little slice of life photo.
I'm going through the entries, stopping at those images I feel have had the benefit of an unconventional eye and dwelling a little longer to try to see and appreciate what you saw. This is one of those images.
Positives: I really like this image, I particularly enjoy the transected dog! The POV is stand out and the boy's gaze to the dog is captivating. The green coloration is excellent - I like the way the boy's top matches. Given the water below, I wonder where you are - on a jetty? On a boat?
Critical stuff: On a wide gamut monitor with most browsers, this image is too pink - it caused me to crank up a modified (colour handling) version of Firefox and the coloration there is much better. Browser colour handling can be an issue - I thought you should know.
