After taking into the consideration to make my digital set more engaging, I've added texture to the wall and the ground. I've also added an educational quote and posters into my scene.
I still have to unlink the spotlight to the table as the light is passing through it. As for now, this is what I have. I also still adjusting the room's light in general because there is a hotspot created by the area light in my scene. In terms of texturing it, I would refine the wall's texture by moving the border of the room slightly higher.
