This is one of my favourite Goblin sculpts, I painted this model a few years ago but I decided to dust him off and take some fresh pictures of him.
You can see I paint in very bright bold colours. I think if I were to paint him again I'd tone it all down considerably. It is a fun piece, so the bold colours kind of work. The rusty blade was a nice touch which involved stippling oranges and silvers whilst also trying to shade the blade in a nmm style.
All this talk of Goblins is making me want to purchase The Hobbit boxed game. I think once I've seen the film it will be near impossible trying to resist buying it.
