Very cool, man. I especially like that new halfling, he has a nice flow and action to him. I've been experimenting with brown stuff myself lately, I like how hard it dries... I can sand it a little easier. I've been using it to turn some ordinary minis in to Medusae for a game we have coming up that features a lot of playable races, and there has been a lot of interest by players in playing things like Medusae, Minotaurs, and god forbid, winged flying monkies (which, by the way, I shocked the player who decided he wanted to play one by getting some from Eureka minis). So I've been doing some converting and whatnot, though I'd like to get into some full-scale sculpting like you've been doing.
I too have had some issues painting black on miniatures, though I'm getting better and trying new things.
Love the new paints too. Keep up the good work.
Oh, on a side note, I almost finished the scratch-built zeppelin I've been working on for a while on-and-off that I mentioned in an earlier post. It's about 2.5 feet long and designed so it can sit on a stand or hang from the ceiling for playability. I'll post some pics in my thread when I get time to take some; all I've got left to do is some detailing then spray-n-paint.
