Alexander and Ben have summed things up well, I think. There is also the fact that a flashy bit or two on Erlend just feels right to me: remember that historically barbarians of all types have gone in for that sort of thing, whether Gauls, Zulus, Maasai, Somalis. At least a bit of flash was something much sought after; made one stand out and all that.
But then, do what you want. He’s your figure, after all, and will look great either way!
