The Goblin King is very close, if not spot on, to how he's described in the book. I thought these goblins might look like the Moria orcs, but i guess having a new breed of goblins makes sense.
I'm also unsure about a large statue of him.... but the detailing in the skin will be pretty impressive, and if he has his crown and is maybe sitting on a throne, i could be persuaded..... we'll see.
I would like a stone giant statue hurling a boulder though
That's true, the stone trolls I guess were rather fleshy and flabby too in a way. Its not that I don't like it so much as I find it kind of gross.
