The assets that are left on highpoly are: floor, floor trim, metal chains, flame holders.
Then texturing everything giving it wear and tear. Then some spider web and piles of sand (might do the sand as a terrain material and sculpt piles on the floor.)
So next week I will finnish with material deffinition and variation. Lighting and final baking of it. Vertex paint for sand on all objekts and maybe and upvector shader for the sand as well.
Story telling elemets and atmosphere and add things as i go to make it cohesive.
