I cannot tell if he is horrified by what he is seeing or just annoyed by something the viewer has said. Regardless of what emotion he may be expressing, the wonderful Charge did a gorgeous job on him! Initially this was just a sketch, but we agreed on a line art with only the brain ribbons and eyes colored in, to fit with what is currently known about him. I have to say I adore the way they did this and for some reason I find all of the wrinkles and general miscellanous lines incredibly charming. Not to mention the fact the ribbon tether is lowered, showing quite a bit of expression to go along with the visual mouth and eye placement. <3
