Howdy,
There are eleven layers in this piece. I have saved each layer to a seperate file so you can see what I am talking about, and will explain a little about what is going on with each. I am using photoshop 7, but there is nothing that photoshop 6 couldn't do. I have never used paintshop pro, because I am a Mac head.
By the by, this is basically a distillation of what I learned from the polykarbon.com and the Mac Hall tutorials. Caviat Emptor.
The line art sits on top at layer 1. The bottom layers have simple blocks of color, and the middle layers have tones.
Layer 1 has the scan of the inked drawing. I inked with a #3 kolinsky watercolor brush made by raphael and scanned in at 300 dpi. I scanned in lineart mode, changed to rgb mode, selected all the white and deleted it. The remaining lines are then toned down to about 70% opacity or so. You'll note my first screw up here as well, as the red of the lips should belong on a separate layer. I like keeping the ink lines free of any color.

Under layer 1, I create a couple new layers, zoom in, switch to the polygon lasso tool, select areas of the same color, and use the paint bucket to fill the areas. If you use the paint bucket, the paint will not spill into adjacent areas of color, even if you are sloppy with the selection. I usually have a couple layers of these color blocks, and it makes it quick and easy to select areas with the magic wand tool to manipulate on other levels created later.

Next I drop a layer of white under everything so far, so areas like eyes and teeth stay white, and also so that any background does not bleed through any gaps in the color. Note that the grey background is only to show you the white shape. There is no grey in the real image.

I create another level on top of the color blocks, but below the line art, and set it to "multiply". The darks are then brushed in. By going to the block layers below and selecting colors with the magic wand tool, I can get quick and easy masks to protect the rest of art. Just be sure to return to this layer to do the brush work.

New layer on top of the last. Set it to screen and brush in the highlights. Note that the grey background is only to show you the lightened areas. There is no grey in the real image.

Two new layers, one each for tears and lips.

Shadows for the shirt are roughed in on this layer.

New layer under the inks. This is set to overlay, and I glaze the dark areas with a black brush set to 12% opacity.

Drop a background under it all. A simple gradient modified with the lighting effects filter.

Stir, shake well, take two and call the doctor in the morning.
Best,
