Thanks! Yeah lightmaps are pretty tricky XD -> http://i.imgur.com/YtZFQ2l.jpg
And I agree, that area is a little empty, but I don't know what to put there, any ideas?
Lol you're right, looks like Asgard in MUA2, but I never played it.
I took my inspiration from Valkyrie Profile 2, Odin Sphere, the description of valhalla in the eddas, and depictions of viking halls, castles, etc.
