I like your clay renders, amazing details. But I think your ruined your composition on your final image.
It feels cluttered (with the material work the details got too much), there are no guidelines, no focal point. Everything is just glowing, there is no moment of mysterious, instead of just lighting on one room and making up a story, you lighted up all the rooms as if a party is going up there. You should leave some negative space for balance in the image. Images with negative space are more dramatic.
You don’t need am interesting subject on each side, you could just focus on one part of the scene and make a story there. Without composition, an image is just blah. Composition is guiding your viewer to the most important elements of your work. Many artists miss it out and focus too much on details. Details are the last thing you should focus on. Next time you should attempt to portray an emotion/mood/story, then add your details as a seasoning.
