Compared to Samurai these were a doddle, especially when so much of the kit is mail, armour or leather. I've even painted the eyes on these little blighters which is usually something I run a mile from as the thought of cocking up a perfectly good face with goggle eyes is too much to bear.
I must admit some of these Vikings have the 'thousand yard stare' but Im attributing that to the light of battle glowing in their eyes rather than any lack of painting skill on my part.
