I've always liked trolls. I'm not quite sure why, but I think it's the mixture of comical gawkiness and crude brutality. People might laugh at trolls, but I reckon they'd do it from a safe distance. Ages ago, I somehow ended up with an undead Mantic undead troll. I liked the shape of the model, but I thought he'd look better alive.
First, I removed his existing, rather orc-like head and replaced it with a head from the recent GW trolls (or whatever they call then now). I then spent quite a lot of time filling up the various rotting holes on the model with green stuff and DAS clay.
After that, it was just a matter of giving him a suitable paint job. I went for the same blue and grey colours that I'd used on an earlier metal troll, in imitation of the old GW stone trolls. I quite like the main body of the miniature but, as often happens, the really nice new head makes up for whatever errors there are in the sculpting of the body.
All ready to bash his enemies with his favourite lump of stone!
