I'm not proficient enough with the technique behind your vision to comment intelligently on it, but the result is startling. I see the depiction of a horror concept characterized by the incernation of pure predatory evil. Usually efforts of this sort are compromised by the artist's effort to soften the effect by adding a mitigating element such as character charisma or romantic background. I see none of that here; any factors that might moderate, diminish or attempt to justify the subject's ferocity are omitted as unnecessary, even unimportant. He is what he is. The moment is the moment, deal with it ha ha. Congratulations. This work is in a superlative class by itself.
The kind of work this must have taken must have been rather tasking, and must have taken a rather lengthy amount of time. I have always been a fan of the realistic effects of anthropomorphic alterations, as well as the kinds of sci-fi-ish transformation that a person can go through, while still managing a humanistic appearance somehow.
The one word I have to describe this is "Amazing". I could never imagine how much time and effort someone had to put into this in order to get this kind of result in the end. The way this turned out impressed me beyond a large number of other things have in the past.
All I can say is keep up the good work, and the only direction you can go from here is up.
