COMPOSITION
I think the composition of this shot is very strong. The trunk is a stabilizing factor in the left of the frame, but there is enough fo the tree in the rest of the frame to provide balance. You have chosen a good subject here, the only suggestion I would make would be try to find some way to have the leg going up and out like the rest of the branches. Then it would really look like a "limb."
TECHNIQUE
Your focus is good, and you have done a nice job of controlling the light in the leaves -- it is bright, but doesn't appear to be blown out. The darkness in the lower left bothers me some, but not a lot, maybe some fill flash, if it were available would help. Also, I think the bw really adds to the picture. Though color would have been nice, it may have caused too any elements to compete with each other, adn would have made the leg very obvious.
OVERALL EFFECT
Good work, and you have met the challenge well. I just have one question for you? Was it not cold up there???? February in Michigan, and you (or your model) doesn't have pants on. Hope you didn't get sick!!! :-)
Rich photo...nice use of persepctive. And one of the few that qualifies for this contest. I like the way the human form seems to blend so well with the form of the tree. Still, maybe could have done more to "hide" the person better..perhaps a wider angle, or different cropping?
I see a leg. Does that count for finding Waldo, finding part of him. I love the angle to the shot. Great idea. Well photographed. Nice focus. The sky appears washed out. Was it this washed out in color? If not, color would have been better. But it's a good black and white. Nice job. Well done.
I like this alot. This is the only photo I liked where the person was hidden by just showing their leg because it blends in with the tecture and limbs of the tree so well. B+W was an excellent choice. Very interesting perspective. Great job!
