I have no problems whatsoever with this head! Vladimir, you are extremely talented!
For whatever it's worth, a long neck has been used in art to depict someone who is shifty, and given the character's occupation (an assassin, I presume), the longer neck adds to the character's overall unpleasant demeanor! The neck tendons may be a bit thick, but I will presume it is part of the design.
I rather like the eyes. Their positioning adds to the scariness of this fellow.
Excellent work, thanks for sharing! Keep us posted as this model nears completion!
