Looking at this photo of my Tigurius up close, his face still looks unfinished. I want him to have darker skin than GW's Tigurius, but I still need him to look finished. This has resulted in a lot of finicky over-highlighting and over washing as the color goes too far in either direction--much like the ongoing battle with several areas on this guy. The base is also unfinished, and will be painted in reddish-grey earth tones to match the army.
One final side-thought--I have always thought GW's newer Tigurius model looks inferior to this guy. It's strange that they could miss the mark so badly on that, considering they have several current Librarians that look pretty darn good.
