This is very nice. I really like the contrast of the striped pants and the curve of the "thing." The bare feet also work well -- shoes would have totally made this shot lose its "child" appeal, I think. Also, I really like the bw conversion that you have done.
Dr. Seuss pants? :D The tones and details are excellent. I love your composition of making it look like someone is climbing out of the picture. DOF - beautiful!
Excellent shapes here. The curvy "ladder" the person is standing on leads you right up the image. I like the dark to light gradient background from the bottom to the top. Just a funny subject with the striped pants. Instantly think of a prison break, as mentioned a previous post.
That's an interesting view. I had no idea what it was from the thumb. I like the combination of the abstract design with the human, (though anonymous), element.
