The scene itself looks really cool! I really like the top-down angle and the perspective overall. As for values, I’d suggest mainly dividing them into three groups: lights, midtones, and dark tones. Use dark tones for cast shadows (e.g., the one from the bed on the floor) and for objects in the foreground (e.g., the ceiling beams). Keep the rest of the room in midtones (you could even introduce an extra value here to accent slightly darker areas if you want), and of course use lighter values for the areas that are more exposed to light. Even just painting the beams darker would already help add more depth. Hope this helps!
