Agreed with your comment there Pirate-Cashoo, the man is hard one to please and that's being said from having to make a murial of people you've killed for him!
Still wow at your handywork here. The realism in the look if uncanny for recognizing the terror in Fort Frolic but love the way you added some realism and even rounding out the face to make his image much more appealing to the eye.
Also very cool style of the lines as well your toning with the white and gray. Allowing the whole to show off the lighter parts and the gray to cover the rest really helps round and flesh out his looks that much more, bravo.
And nice touch of red and green, like all splicers Cohen always attributed a faded actor look on him, bravo Pirate-Cashoo.
