Provide details about the setting. Quality is more important than quantity. A few accurate, original descriptions will accomplish more than a list of mundane information.
Introduce the character into the scene. You can do this simply by mentioning what he is doing, what he is thinking or why he is there.
Describe the character using unique details. This could include his appearance, his movements or any other aspect about him. A few details will be sufficient. Again, avoid long lists of information.
Allow the character to respond to his environment. Consider how it looks through his eyes. Have him interact with it. For example, if the character is standing under a waterfall, how does it feel when he puts his hand under it? This help the reader learn more about the character and the setting.
Continue with the scene. All successful scenes contain some sort of conflict, whether physical or emotional. Allow the character to keep interacting with the setting throughout the entire scene.
