While it's a great idea, the orange tint doesn't work for me here. More uniform focus on the front three figures would also be better. The blured background is great.
Nice idea and pretty good execution. The image seems a bit too high-key for me, consider a fuller tonal range, and sharp focus/DOF for all 3 foreground paper people would help. I like that you've created a feeling of many, and yet preserved subjects for main focus in the foreground.
Great idea. I was born on the day the world population became 4 billion but I couldn't think of a way to portray that. I love how you chose to do it. Back to bump you up to 8 for creativity and a pleasant pic.
Creative, yet simple. Artistic as well. Congratulations on putting together a photo that could find it's way into a frame. Well done. Good luck in the challenge.
Very interesting take on the subject. This comes across as more graphic than photographic, yet still brings a sense of the drama and significance of the milestone. 7
