It's 23:30 PM and I call it a Day. I was not too diligent today but the terminators are as good as done and i am confident that I can do the rest of the army in the next two days leaving me with two days without painting.
The solution to the face riddle: It's the Chaos Marauder Champion from the Avatars of War series. I ordered this fellow just for the head. Since he comes with two head options, the model is still useable so expect a giveaway post soon after the Austrian Championships.
