Nice simple composition. The highlight on the cheek is very nice. I would have liked a larger picture. The grain of the wood is almost teasing your eyes. You can kind of make them out but not the details. Using B&W on this one makes it really moody. The black background helps to really bring out the moon. Gave you a "9" on this one.
It meets the challenge. I think it´s an original idea, but for me it hasn´t enough interesting. Perhaps, you´ll need another background colour to make this picture more interesting. I don´t know. It´s only my opinion. 4
