I acquired a couple additional Windsor & Newton Series 7 brushes from DickBlick.com to accompany my trusty size 1 that I've used for years. In particular, I used the 000 (or 3/0) from the series for the facial features. Along with the optivisor, was able to paint the eyeballs and eyebrows.
Although still not great, I think this face is somewhat of a step forward over the previous faces I've done in this series. There is still a long way to go until I'd consider it pleasing to the eye, but one step at a time...
The Vallejo Black Wash replaced the black ink I used previously for black lining between various pieces of clothing and items. It leaves a bit more natural dark separation than the ink which I like a little better.
