I was surprised that some of the concept art and in particular sketches of wooden structures had clear Viking-era influences, both in architectural and smaller, ornamental design. You did your homework. I certainly hope to see more of that. The one thing I am still curious about though is the music. I've heard some tunes, medieval true enough, but still lacking in that distinct, perhaps non-continentalized view of Scandinavia that even had it's own, romantic revival back in the 18th centuy. I'm not exactly talking about Edvard Grieg, but.. well.. yeah. Maybe I am.
Either way, best of luck with the project. Looking forward to seeing more material.
