The Ork has great skin tones, and the rusted chest plate is perfect. Unfortunately, it's a poor shot that doesn't really do him justice. The only thing I would change is drilling the gun barrels out, but it's for my personal collection so I don't mind too much.
(He is one of two Skinhead Orcs that act as a bodyguard for the leader of my drunken Irish Aliens in our Shock Force games.)
The Dwarf I love due to the seamless blending on the armour and tusks. I would put this down as my current quality of work, given the right fig to work with. When you see the fig in real life, the armour has a laquered effect like samurai armour.
Everything is just right with this fig, and until yesterday would have been the one to show off...
