Sure! When we say "highly detailed scenes," we mean that you should describe every aspect of your story in great detail. This includes descriptions of the setting, clothing worn, actions taken, emotions felt, etc. This will help readers feel like they are actually in the scene and experiencing it firsthand.
As for writing about what characters are thinking, we mean that you should provide insight into your character's thoughts and feelings throughout the story. You might include internal monologues or other means of showing what is going on inside their heads. This will help readers connect with your characters and understand them better.
