it can look beautiful

I agree that your small room can look beautiful.

Your floor looks clean, and it is obvious that you wash laundry. Wash your shelves and dry them with a cloth. If your clothing will not get mildew, fold it neatly or roll it (fewer wrinkles) to store it on your shelves.

Stack your books and papers neatly - either flat or vertically, depending on the moisture/humidity level of the air in your climate.

I see that the wooden bed and another piece of brown wood furniture might benefit from some cleaning followed by an application of furniture wax.

I see that the pink base for the desk/table by the bed would benefit from wiping with a damp cloth. Wipe off all surfaces of your chairs.

I see that the wall near floor level is discolored. Find out what might be done to clean this.

You can make this room clean and beautiful! Best wishes for success.

If you arrange it properly then it will look good. You can place some good bedroom furniture(Oriental Creativity) in your room then it can look better.
