This decapitated looking head looks amazing. I really like the muted colours and the look on the guys face, it has an eerie undertone.
I also like the writing in his beard. The angle of his head, the 'gone' look in his eyes, the odd scull; showing the brain, the chiseled nose, which looks sliced, the scars under the eyes sockets, and the cracking face.
I think you've mastered a real look that makes me want to stare at that face.
I also like the fact the mouth is slightly open, as if he was speaking, or taking his last breath.
The last 'inhale'...maybe...before he was sliced at the neck.
This is beautiful in a soft way.
Great job.
edit: I also liked that it was framed. It made the illusion a little more twisted.
His eyes look at you. Such a good job on the eye area.
Followed up by nice eyebrows and shading, showing contrast when leading to the open brain.
The bolts in the corners of the frame, to me, depict jail. I don't know why I see jail.
I like this piece of art. It moves me. I think it's believable.
It looks like it's plated on glass. That's different.
This is very cool.
