it's very difficult to pull off good NS with such a small subject. But your subject has a great shape and is cutting through the horizon line, so it works. And the picture is meaningful, too, with a sense of losing oneself in vastness... on purpose.
Nice shot, maybe a slight bump in contrast or a B&W levels adjust. I'm sure you'll get some comments about your border....I rate only the photo, but it seems I've been seeing lots of negative border commetns lately.
I don't know if it was possible, but it would have been very cool to get the camera a little lower so that the horizon was below the diver. I do really like the negative space here. I love the smallness of teh person against the ocean and the sky. 7 from me.
It's not that bad...really...don't jump!! Fun photo! Black and white suits it well. I'm not sure about the border. It seems to dominate more than it should. Maybe make it a touch more simple.
