<s>[INST] This is a part of my story's first chapter. Please, tell me if I need to add or remove something. Here is the part:

"His chair made a soft creaking sound as he shifted his weight from one side to another. He tried to calm himself down, but his mind was racing. Suddenly, he heard the sound of footsteps approaching from the opposite side of the room. He felt his heart sinking as he slowly turned to look behind him."

I think it's pretty good, but maybe it needs something more. I've already introduced the character and the setting before this part.

Here are the things I'm considering to add/remove:

1. More sensory details: Should I add more sensory details like what he smells, feels, or hears besides the creaking sound and footsteps?[/INST]
