This image really is appealing. It appears to capture an expression and emotion that we normally associate with people. It's hard to look at that expression and not believe that the giraffe is expressing 'love'.
The eye is led dynamically into the picture through that long neck. Almost like an arrow, it directs the viewer to the crux of the image - the entwined heads and that expression. It is this that really holds the viewer's attention.
I think the voting reflects the problem people had with the image fitting the challenge well. For me personally, there is contrast but not high contrast. Bumping up the saturation may have rectified this, but I feel something of the lovely simplicity and charm of the image may then have been lost.
You have,though, produced an image that is a pleasure to look at, and that is more important than scores in my opinion;)
This is such a cool capture! Tack sharp focus with good DOF too. My only suggestion would be that the color tones could be bumped up a hair. The composition is outstanding. Great job.
Great effort, I would have liked to have seen the green a bit brighter as the contrast colour. although I guess that the white in the faces contrasts the black.
Like the pic as well - good score
