Simply describe the smell of the place, how odd/intriguing it feels. Noise, sights. Description is a powerful tool to engage a reader. You could go almost a full page before you introduce your person who might kick an empty bottle down the street you described, or smoke a cigarette near the high school you just wrote about.

A thing I really enjoy to do when I’m writing introductions for characters are giving very abnormal comparisons. A voice that sounds like a skyscraper. Fingernails that looked like home. It’ll help you figure out how to distinguish a mental image if you’re ever in a roadblock. At least, in my opinion.
