Please, be considerate and create some system for heads to scale with the rest of the body! I mean, sure, heads look proportional if you choose to play a tall muscular character (or a fatty), but if you choose skinny with small torso size, the head looks about 20-30% bigger than it should be (to the point the head is almost as big as whole torso, especially with wood elves that are naturally short).
(also while you're at it, add some actually usable, normal looking hairstyles, not everyone wants to play something that looks like a 50+yo frigid military officer or a glamour ***)
