How does Terry Brooks use imagery in Running with the Demon?

Imagery:

"The man looks the town over as he would a corpse, remembering it when it was still vital."

"The park had seemed much bigger then, a vast, sprawling, mysterious world of secrets waiting to be discovered and adventures begging to be lived. At night, sometimes, when she was abroad with Pick, she still felt as she had when she was five, and the park, with its dark woods and gloomy ravines, with its murky sloughs and massive cliffs, seemed as large and unfathomable as it had then."
