This shot has some very strange lighting and is blurry. I feel that this photograph belongs in this challenge like a beautifully composed poem belongs in a corporation's annual report. Your first clue could have been the extra description that you felt needed in the title. There are photo competitions on the internet that allow for submitting your best photo (or a photo of your choice), however, I believe this site is prompting you to take shots that you wouldn't have otherwise by followin the description of the challenge. I hope this comment is constructive. If your photo finishes lower than you had hoped this might be the reason. Good luck.
For me, this image has some serious drawbacks. The mask does not seem to be in focus and it appears to have quite a bit of noise. The bright spot above the mask distracts from the mask itself.
