just another point to make, because now im lat for a different class, palette unification imo is almsot always a good thing. mine uses 12 colors, and i think my gaps might be too big (though not so if i lightened that dark dark blue) where yours and helms use 18 and 17 respectively, but helm's edit however does something yours hasnt quite yet gotten to which is to make things look smooth, this is a byproduct of both his dithering and the new palette hes employed.
