I know that stuff as additional sliders and such maybe are a huge undertaking because it's directly related to the engine...

But if not, then there are some alternative options to that:
- Add more faces! It's pretty unsetting to have only 4 options in some races, when the other features (mouth, nose, etc) barely alters them
- Add more features. Derplander's stubble is already in a ingame model (see benchmark). Also there are a lot of inconsistencies on what which face can have and some other's don't, for no clear reason
- Let us stack 2 or 3 face paint options! Why I can't have big eyebrows AND freckles?
- Bump up the resolution of the face paints. Seriously, most of them are blurry on a distance
- Related to the character creation menu: For the love of the twelve, let us preview the combat sounds of the voices

Not related to added customization but a bit:
- See the emote menu, the face expression tab? Can we have a checkbox to enable us to keep an expression indefinitely?
