The first render shows the application of the wooden desk here I went for sky texture for the comfy sun lighting and I also made sure to not over do near the table, the cup ,textbook and the chair shows that it was recently used which also adds storytelling.
The models used in this render (chair and desk) are available on my fab marketplace so if you are interested make sure to check out.
