I like the idea and I think you've technically executed it well but I'm lacking something interesting in the reflection in his eye... It's not bad at all but I think if there had been some sort of story one could interpret going on through the eye the pic would just be rocking.
Had the same feeling, was thinking of shooting it at a different angle to try and get either more of myself of something else, I did also ponder maybe having the garden landscape in but is very hard to keep him still so may try this when its sunny next as he'll lay in the sun for hours.
Or you could "cheat" and print something interesting on a large piece of card-board and then cut a hole for the camera in it and shoot. This way you could have a crime scene or mona lisa in the reflection still without using photoshop
I love that idea! It would even work for a 'self portrait' of your own eye! I guess the trick is, making sure it's lit well enough. Dan
