So, in my little fantasy thing, Side Quests & Halfling Tasks, all my Elfs have very drastic skin colors like blue, yellow, purple, etc., etc. So I have this strong idea for how to do Half-Elfs in this world, but I can't get it to work properly here. At least not yet. With Half-Elfs, the Human skin tone is the dominant one, however there are traits from the Elf parent that are noticeable -- the ears, of course, remnants of their eyes (he is supposed to have red flecks in his brown eyes), and there is almost an iridescent sheen to their skin. So this guy's skin should have like an iridescent sheen of blue to his skin that I just couldn't get to work. Hm. I'll keep trying!
