If anyone has used heads from other manufacturers to add variety please send up pics. I am wondering if the ones from Mad Robot are big enough for 32mm, since they are sculpted for heroic 28mm. That and sculpting your own Togruta or Twi'lek heads too.
Rebel heads
I had bought some Mad Robot minis to practice painting upon. Their weapons are just about on scale ... the bags and packs the same ... I found the heads too small.
Mel has some alien heads up on Shapeways.
found them, unfortunately after I bought some other nice ones. Bigger variety here.
I bought the Shapeways heads. They are nice and clean with crisp details. Cant wait to slice, dice an put them on. BTW, fun fact, they smell minty fresh!!!
