This image is definantly in your face so I will address this from a couple of angles. I for one love in your face horror type images.DPC as a whole does not. There are some people that do, so you will get some good scores from them but for the most part you will not get a good score here from images with a horror element. Of course there have been a few recently that did well so maybe that will change:)
Another thing that I feel kept your score down in this challenge is the darker tone in general. As you can see by the top scores, Bright colors and tones were what the voters were looking for.
Ok so in the end scores are less important than if you like the photo so lets get to how I feel you can improve that. The background is not really helping you here. for this type of photo an entirly dark background could have worked well for me but the half white half black just doesn't work for me. maybe if you had turned the camera so that the dark parts were behind the entire frame. Then you could have used levels in your editing program to help darken and even out the background. the photo seems to have some noise which will happen of course but one way to help have less of it is to expose a little more. with your f 2.7 and ISO 50 are probably too low for this lighting. keep in mind that you can darken the photo later if you want that type of mood. a higher f number will help you get more of a depth of field which will help you get more of you in focus
The first thing that came too my mind seeing this was Kane from the WWE I am not sure if this is what you were going for but if so you did it well. Keep up the good work and continue to think out of the box. I hope this has helped.
