Yeah, bit of progress:
Bossk: Eyes and mouth are all done. Just got to tidy up spots on the flesh. Clothes are nearly done. Gun still to do. His eyes were a bit of a challenge, being very cat-like pupils, but done horizontally rather than vertical.
Fett: Still dunno whether that green for the armour is right. And i don't want to chance it till after i've beat it up. Starting to block in the cape.
Zuckuss: Picked out details, including the eyes and whatever the hell that mouth thing is being based in Gunmetal. That "bib" affair appears in turns both metallic and slimy, so i've gone with a compromise.
