Process continues on drawing practice. I've tried to pencil out a few new characters for my 4E5 game, which I've tenetively given the working title "Mad Science". Since I only have internet access in the lab I'm visiting, I don't have a lot of resource material to base characters off, and you wouldn't believe how difficult it is to draw a good looking hunchback until you've tried.
I've also spent a lot of time playing around with Inkscape, which I'm gradually becoming more confident with. The more I play around with it the more tricks I learn. The most important one is "don't use Inkscape on a borrowed laptop with only 256 Mb of RAM if you can help it, because it often takes several minutes for Windows to thrash around enough memory to open a dialog window", but there have been a bunch of other useful little tricks I've figured out through trial-and-error plus sheer bloodymindedness. I figure if I keep plugging at it for a month or so I'll really start to get properly comfortable at creating Inkscape art.
Here's another piece of Inkscape art to wet your appetite. Sorry about the size, and it also probably looks best on a light background too (i.e. new GameDev.net, rather than classic black):
