Well Done!
In my opinion, y
you can make it really conceptual if you make the camera angle very sharp, something … like deep space, make it desaturated and put some volumetric light from top…
Well done. Although a touch of organic lighting might help the space not feel so closed off. Just something to let you see a little into another room or maybe just a window with some light. Like the photo at the bottom of Adrian Schulz work that you gave a link to.
