You have done a good job of camouflaging Neo through photographic technique.
I think the lower 1/4 of your crop weakens the image, its takes away from the busyness which is your camouflaging element
he certainly blends wel, but the conversion to two tone makes this less of a feat. Is he a yellow dog on a field of yellow leaves or are the leaves green and the conversion hides him? Other than how well the critter is hidden, it isnt a great shot and Im not sure if this is camoflage or editing a scene to a tone reduction to create an effect.
