Painting over work that was painstakingly done previously? I dismiss that concern with a gesture!
End result:
Started with tidying the face up a little, adding a large area of mixed colour on that shoulder pad and then going for the forced shading and smudging paint around to finish.
Much better and much less Miss Priss than before, I reckon. Most enjoyable. I'll probably go through the rest of the (unpainted) minis I have to match this one and do them in between army units.
