I haven't used the pen tool (or photoshop, actually!) in a while, but the way I normally do it is make a solid shape for the silhouette, and then using this setting on the pen tool
(does that even have a name?)
I start adding subpaths to cut away parts of the silhouette to make the line art.
It can be a bit fiddly and sort of time consuming, honestly! I'm told it's easier in Illustrator or Flash, but I've only used Flash very very briefly, so I don't really know!
Paint tool Sai has a vector-ish inking tool that lets you mess around with line weights once you've already put the lines down-- I think that's what Devicho uses, actually!
