Thanks to all for your kind words.
To answer some of the questions:
I paint in oils, wet on wet. My mentor for painting faces, especially the larger figures and busts, is Phil Kessling. Phil has written many articles and given many seminars on the subject, and I have 'stolen' all of it. As a consequence, my flesh formula is Phil's; at least what it was when he last published something.
BASIC FLESH MIX
Basic flesh mix for oils is Mar Orange or Mars Brown, Cad. Yellow and Tit. White. Proportions are not precise; just mix until it looks right. Variations can be made by adding a little Cad. Red, Purple Madder, Mars Yellow, etc. You can vary the base color slightly on every figure so that they do not all look the same.
There is the danger of going too orange with this mix, so care should be taken. Over the years I've made little paint chips of successful mixes as a guide to avoid going orange.
PRIMING
Believe it or not Pete, I use Rust-oleum Flat White right out of the can with good results on both resin and metal figures 54mm and up.
EYESMike, the eyes are hand painted. To me the process of painting a figure is as important as the final result, and the eyes are the most important feature and fun to paint. When I look at a figure I always look at the eyes first. If the eyes are well done, I can forgive some mistakes in other areas. But, if the eyes are bad, the figure cannot be saved.
Airbrushing is a method, but not mine. My weapon of choice is a W&N Series 7.
As for a book, I think Phil should write one.
