By choosing a theme, you will be able to decide which paint colors to use and what accessories you can add to achieve the theme you have in mind. In addition, having a single theme will help you arrange your furniture and belongings to create a proper flow of the room.
You can also consider painting the walls of your space; however, you need to consult your landlord if you are allowed to change the colors of the room. If you are given permission then you may want to consider using lighter colors, especially when you have a small space.
