David,
I echo what everyone has said so far. It is defenitly good to pick a medium first so you dont spend to much money on paint. Also a good quality figure. All my better painted figures are the ones that were scupted and cast in a very good quality. I know it is kind of tough cause you dont want to spend too much, and waste a good figure on a poor paint job, so you kind of got to find a happy medium. Get a subscription to a couple good magazines (Historical Figures) and ask lots of questions and most important accept any criticism and put it to good use. Also try different, out of the ordinary things to see if they work for you. (I've used chalks, inks, rub on silver wax, mettalic paint pigment powder, craft paint, oils on top of acrylics, acrylics on top of oils, watercolors. All with success and disapointment). PIck out some of your favorite figure painters and try to imitate their quality but with your own techniques or combination of techniques of yours and others. And, last but not least, take your time and ENJOY.
