Roc, the comments about the flesh tones are quite reasonable. What you see is just the basecoat flesh. Nothing done to the face in oils yet... except for the eyes. I've been kicking around some ideas for delineation of the helmet, and may well go for darkening the pie-shaped pieces of the helmet, to more resemble a slightly oxidized iron color. Maybe a couple washes of sepia or umber to do this.
