Not super, but enough to just look damn odd. I did some screwing around in photoshop to see how close I could get without changing the whole thing. I did not attempt to mess with the bow tie, boutonniere, or the nose, which is also off quite a bit but not super easy to change because of the angle of the photo. I recolored the hair mostly black, whitened the skin tone and the gloves, made the eyes larger and moved them closer together, and I yellowed the eyes and teeth.
Even if they had made this, but the exclusive BANG flag gun exclusive swap out was still the hand that's not the one holding the fish like a gun, I would still have to think really hard about it. That ****'s just stupid.
(it's obviously not in the photo I used, but I also cannot stand the the green chemicals in the vat are about to splash all over his leg.)
