Here is a medieval bedroom that I created using concept art made by Giovanni Silva for Knightfall: https://www.artstation.com/artwork/Z5o9D1. I tried to match the concept art as closely as possible. I think the most difficult part was matching the camera angle and the lighting. The scene is assembled in Unreal Engine. The props are made using Blender, and the textures are created in Substance Designer and Painter. All the props are made by me from scratch.
