Two other artists I looked at are Julie Bell and Boris Vallejo. The backgrounds they've painted are as close to the ice like texture I imagined the Palace to be covered in. I also like the way they've been painted. Plus the way they have also painted the rocks in some of the pictures is also what I imagined the Palace of Death to look like, at least the parts not covered in ice. There is also one picture of a mountain scene which I thought would help with the outside to the cave. It describes 3 kings situated in different points at the entrance.
