My theme will use Sci-Fi architecture taking inspiration from Prometheus, alien and halo.
The idea is a throne room inside of the mother ship of the emperor of the whole Andromeda galaxy. The throne will overlook the galaxy out of large windows. The throne itself with have wires and sockets plugged into it that download information on everything that is happening throughout the galaxy to the emperor.
I plan to keep this scene small and VERY detailed. Sci-Fi interior architecture and throne in the foreground with meteoroids in the mid ground outside the window and the galaxy along the galactic plane in the distance.
