Here's the first of two models I painted using a somewhat haphazard approach, attempting to put into practice several techniques suggested by Jeff, Sean, and others. I'm pretty happy with everything save the face, which looks a bit gloopy to me even now despite thinning the paint to near invisibility (or at least so it seemed on the brush).
I didn't even realize the figure had a lion on its chest until I shot a photograph and zoomed in. I knew I was taking a chance, but I was compelled to apply my drybrush. Lo and behold, it worked.
