Enzie, I'll send that message on to Marvin. Our model and mutual friend is doing well, although sitting in one position for that long has not been easy for her.
Dianne, the paint system can be seen at this link:

As for the brushes and how they are laid out, I'll describe it now and post a photo later.
The brushes are put in rows that match each value. There are 3 brushes per value - small/medium/large brushes. Even though there are four possible colors per value, you don't have a different brush for each of those colors in that value string. You simply wipe your brush if you want to change colors, and you only use that brush for that value. For example, let's say you're starting the portrait and you want to lay in some darks. You take your value 1 brush (1 = darkest color, 9 = lightest) and put it in your value 1 paint. You might lay in some black, or some raw umber mix, or some red mix, but you're only using one value. Then, when you're done with that value, you move on to another value string, using its designated brushes. It sounds more complicated than it is.
I like this system because my colors are cleaner with less effort.
