Great work without having to be all clean and neat to get there. The dark and busy style creates an overall sense of fear, doom and surrealism like a living nightmare standing before me in a very immersive and threatening way that has my hackles up. It fits perfectly the persistent feeling hanging on me since the horrific nightmare I had last night and could not wake up from. Thanks for giving my angst a face so I don't have to try to explain how I feel inside today. Sorry for misplaced critique. I'm new here but I'll get the hang of things.
This artwork reminded me (like a lot of people I suspect) ok The Slender Man. However, I guess one could come up with some lore inspired by this picture of how the 'no face' aspect that people so often asscosiate with slenderman is actually a veil or a mask that hides the real face underneath. A face which has emotion, form, and most prominent of all...TEETH.
Ahhhh, just imagining the image of Slender pulling away the mask to reveal a bloodied, gaping maw (like what you've magnificently drawn) gets the creative juices flowing.
