Yeah. I don't think this is meant for normal gamers, it's more nisched. It seems really awesome though, I really want to play this.

Viking swords ARE european.
And yes, some vikings wore Chainmail, but not big body shaped armors like the one in the picture.

You've also started detailing when you aren't done with the basics. Get the basic shapes right first and then add detail.

The beard needs to go. It's shape is weird and it defies gravity, redo it from scratch.

Anyways, good luck.

A few crits.
Vikings dressed mostly in leather, Iron and hides. In your picture he's wearing a big chunk of armor/chain mail, which I doubt the vikings used.

The axe blades are too small. The shaft is too long and to thin, it would break from one swing. Viking axes are shorter, with huge blades. Check som references.

Why are his legs bare? It's cold up north. I'd add some greaves and big boots at least.

It's a king in a castle. Vikings had chiefs, not kings, and they usually lived in simple villages. If he's a veteran I think he should have lots of scars.

It still looks like she's doing the twist. Make the legs steadier.
