My first impression is that you probably got some low votes on the whole "is it a silhouette or is it a shadow" debate. Personally, I did not vote silhouette images any differently that shadow images, but I know some did.
The thick black border is a little distracting. IMO lees is more on borders. The wrinkles in the backdrop are distracting.
The composition is good. I like the way the frame is filled. The diagonal line created by the hands and arms takes the eye across the whole picture. The red tones add a sense of scariness to the shot. Good choice on the color.
I hope this was helpful. Feel free to contact me if you have any questions.
This has a lot of potential. What comes to mind is shadow plays, a la those things they have in Bali. I think this would have been better if there was a story - perhaps meaning two people interacting in some way - making the shadow. The light at the top is a bit distracting too.
Seems like you are confusing silhouette with shadows... they are not the same. Nice image, but your score may suffer due to the fact that there are no shadows.
