grievous is double-jointed... so the arms took a bit more time than expected.
still have to properly set the eyes. they're not 100% aligned/scaled right now.
i didn't bother making him manifold by connecting the arms at the shoulder, but netfabb saved me a lot of time and it sliced properly, so it should be ok. probably needs a base or he'll topple over.
fingers look a bit weird after subsurf modifier, and i messed up on the back tris-to-quads. other than that it looks alright, but print it at your own discretion as usual.
i don't think there's anything else outstanding, but i welcome your comments and criticism should you find anything needing repair.
