Sampled the colours from my original Rei piece (great suggestion, DA, thanks) and added a bit more shading (face, black bits on suit, the box on her hip). Made the mouth a proper bezier polygon and shaped it - I think it looks better. Adjusted both eyes to try and more closely match the source image.
Verdict? Derpiness averted? :)
