May I suggest an old sprite of mine for this?
it's based on an outline made by st0ven, and he also had a version

I remember I was very fond of not using outlines back then and feeling like I had everything figured out, I was so cockssure about it I even made a big flamewar out of Egoraptor taking a potshot at it.
But I can see a lot of bad clusters and not very clear lightsource now....so it would be nice to see like a thousand ways it could be better, cause I can see enough bad in it to know it's wrong, but probably still too biased to tear it down and rebuild myself.
so....please? :p
