Well, it is easy to see what might need to be tweaked in other people's work. We just get so close to those pixels after a while, that another pair of eyes is useful. I have a neighbor and a couple of colleagues and my former art director whom I can trust to give honest evaluations and suggestions. If you do saturated colors for the non-humans, you might want to color the eyeball itself a little. I'm thinking of the spice-eating navigators in Dune, but there are other examples. Jaundice isn't a matter of fiction. As for the hair in brows and moustache, it almost seems that you need a few stronger strokes to balance with the fuzziness and give it more direction. And I don't think there are as many hairs in the philtrum directly under the nose as there are next to it on each side of the upper lip... but I don't shave. ;^) Carolly
