I'm back again with a small update. I've added the rustiness to the Skullhama, looking pretty nice, eh? And then some bad(ish) news - my warhammer stockist here (in russia), has no devlan mud... so I tried using some purple wash and I think it turned well enough - not so dark but it should do. The rust was just drybrushing blazing orange over stuff (not what I originally planned actually - was gonna highlight red with it). Have a look at the pipes at the back, they turned out well.
