Descriptive writting exercise. Prepositions

Within the city walls a story lies, A story containing gloomy skies and bridges tinted with rust. Beyond the dark and lonely buildings there is a mystical and magical spirit. Inside the heart of the city, weary students wander.  Inside they are young yet their youth appears drained, a lot like the city in which they are held captive.  Inside the storm is what once was a bright and cheerful city. Above the gloom pigs are flying confirming that its the end.
