I've been following this as it progressed and have been impressed every step of the way! I must say that the final version looks terrific!
When it come to scary demons, your work has always been among my favorites and I've always been a great admirer of your texturing techniques so well exhibited here. If I were the type who gave out ratings, this would be a solid 10 for me but I still have a couple of nits (guess I should explain that to me 10 would be based on originality, impact and style rather than perfection) dealing with the horns... IMO, the rather pronounced roughness of their edges makes them appear a bit flat and smoother edges might help. I also think that the flesh (where it meets bone) might appear less flat if distinguished by some highlights and shadows. Still overall, I find this outstanding work for which I have deep admiration. Great job!
