, not all of our people will be dirty all the time.
I actually was thinking about putting, down near the bottom of my mod wishlist/to do list having a "bath" mod for this specific purpose.
Dirt accumulates the more you sneak around in swampy ground, and bathing helps. Possibly having some sort of reaction bonus based upon being squeeky clean or penalty based upon smelling like someone who just carved his way out of a dragon's gullet.
Also, using the character creation menu again, today, I'd have to also say that there's really no reason not to have full RGB color sliders for just about any of these color options.
Eyes, for example, could also be full RGB, with an option for heterochromia so that you can make that one blind eye thing regardless of which color eye you want in the other. Tattoos and facepaint should also have little barring you from whatever color you want. The game already supports full RGB color selection, so there's no reason not to let the player have access to it.
