I like it. But as others have said, it looks slightly too blurry. Things I do love though are, the amount of detail you have used for the entire head, especially the mouth and eyes. The blood also looks very nice, as with the tongue which looks great. The main things that really stand out to me in this piece is the depth and shading. They are both great.
So basically, I reckon that looks exceptionally good. Just lower the blur slightly. 8/10
