I'm not superstitious, but this picture sent chills down my spine. The way the picture is set, I think a nightmare is an understatement. Because of they way it's taken, I say it's very good quality. It actually looks like you took a picture of the real thing. Especially the eyes, as some sort of gateway of the soul. It speaks out in more ways seen, and that is what really grabs the attention of most individuals. If I have give inspirational words, I would say whatever you accomplished will really get you ahead in the manipulation of arts. Bravo!
I didn't need the sleep anyway. Those eyes are the first things that popped out to me, and they do pop *out*--which is odd, because they look like they're supposed to be sunken, but those pupils are very prominent. The mouth is...ah, freakish, perhaps? and the ambiguity of what the heck the thing is anyway adds to the horror of the image. The use of light, darkness, and shading is very effective. I love the light bloom on the left side contrasting the deep shadow on the right. The film grain was genius. All in all, I can find nothing wrong with this. I only have praise. Granted, I offer the praise with fear in my heart. Well done!
Definitely CreepyPasta material there. This will surely keep the kids from sleeping at night. Could only be better if there was a written Pasta about it... which I don't doubt may appear around soon if enough people see this. Congratulations.
