Highlights are as they are because it's supposed to look wet and/or slimy.
Changed this however to fit current lightsource and added eyelid.
Not sure how to go about fixing these: "the teeth look a little sloppy" and "add more detail to it like some freckles to make it feel more aged". I know what you guys mean but implementation is escaping me. The large area of highlight on the head is certainly a big quality killer for me right now as well.
Yes to all three of your questions bengoshia.
If someone were so inclined and had the time, an edit ( even in red pixel ) would be much appreciated.
Thanks for the input so far!
