I started by blocking out the meshes and lighting to get a feel. Then, I added details in the form of wires in Maya. Afterward, I blocked out the materials and painted all the textures in Photoshop and Procreate, using a repeating texture for the walls and floor, while the other assets use a collage texture. The only elements not utilizing textures are the lights and wires. I then refined the lighting to create a more mysterious atmosphere.
