LOL... oh yeah... couldn't stay away. You have some interesting projects.
If you get real hair eyebrows you need to trim them down and into correct shape, as the eyebrows can sell or kill a piece. You can get a generic bust with David Bowie's face or you can get DAVID BOWIE. If you follow. Then try to do the make-up as if done for real... just giving it that hint of an upwards angle.
I'm still more inclined towards sculpted eyebrows, especially when you have to have make-up over it. It may not look exactly real if painted over hair eyebrows. Your call.
The change to the pupils really gave it a punch upwards and I must say, the eyes you sculpted on this one came out pretty damn good in the first go. :thumbsup
