head for Marneus Calgar

Posted in Custom Workstation

Does anyone have any ideas for a suitable head for this custom? (the bionic eye would have to be sculpted of course). I am using a NECA big daddy bouncer as a Terminator armour base, but if anyone has a better idea, I would be most grateful. If one requires images, 'Lexicanum' would be most useful.

Postscript-could someone kindly tell me how to put images in posts?
