Really cool shot Rob; appears to be a drone shot? Nice composition with enough space on the left. B&W works fine here with all attention devoted to the head. Different water motions hint at how he was formed.
Fantastic shapes and textures. So much to run the eye over and enjoy. I like the subdued palette however you achieved it as it reinforces the repeating patterns.
I love the sandman. you can see the eye nose and mouth clearly. Just beautiful. I also like how the little shapes in the sand work great with those in the water. They are different enough to make the two seperate. I think black and white can work here but I love the blue color of the water as it helps to seperate the shapes.
I appreciate the face but what I really like is the disciplined processing. What a gift of light for the photographer. There is a whole spectrum of blues and blacks here and the overall darkness creates a great mood.
