Regulus Awesome: I wasn't try to adhere to his current design as much as I was trying to show off a more believable facial structure. (The mullet being added on for shits.)
Right now, there are some glaring flaws that one
could call "style choices", but that'd be a cop-out. First, I'd kill off the strange black lines that cause a hard-edge to appear in very, very odd places. The lighting on the ear needs to go. If you think about the structure of a head and where the light is hitting, there wouldn't be highlights on the ear, correct? Unless, for some odd reason, the ears are sticking out so far that they're able to catch some of that light.
Maybe this quick mockup (which is similar to the current, less-realistic version) will make more sense than the Billy Ray Cyrus look-a-like.
