No pencils, I inked over them. Matt said the exact same thing at Kapow.
I think I know what you mean about the reverse highlighting, it's just something I've never 'learned' to do. Any advice you have would be more then welcome.

I was trying to find an old example of shading I had to illustrate the point but this place is a mess, so I can't find it. It's easier to understand reverse highlighting than to explain it really, once you've cottoned on to the idea it makes more sense. If you have a look at someone like Frank Bellamy, who was a master of subtle yet dramatic shading you'll get a good insight to what I mean. Bellamy is probably too -old school- for The Prog though and I'm guessing you're into a bolder style of shading. Still the principle holds true and I reckon it's worth checking him out.
The general guide to reverse highlighting is to shade darkest where the boundary between light and dark occurs. It works best when a subject is lit horizontally against a light background, the idea being that the reflected light fills in the shadows slightly. Don't use it in every case because you want to make use of dramatic lighting, for example, where objects or people are emerging from shadows.
Another, more general tip I would mention to pay attention to the negative shapes when shading because they'll help describe the contours of what you're shading, like hair, drapes or clothes etcetera.
Anyway I hope that some help.
