Of course the wrongly made bucket ended up haunting me... So I took my greenstuff out again and rolled a nice piece to make the needed shape. I left it to set and later I covered it with black. Maybe I should've got some sort of a glossy thing to make the helmet shine a bit? Oh well, maybe some other time.
While I was fooling around I also painted the engine intake vents, the warhead launcher wells and all the blue markings of R2-D2. Now I have to come up with a better designation for it. R2-F6? Dunno, I've still got time.
I doubt I'll ever post this much in such a short time again :p
