Correção de texto: Composition

Hello, everyone. I'm a english learner (pre intermediate) and I want to know how good (or bad) is my writing. So, that's my composition (it's a little text XD) :

The future that I want

Perhaps it won't happen, but I dream one day live in New York. That's an amazing city, which people from everywhere makes then a "little world".
The culture, places (specially the Central Park), pubs, theatres and many other attractivies of the "world's heart" are good reasons to meet then.
As everybody wants to live there, New York is a expensive city. So I need to study hard and work as well to get my target.
Every night I think of walking down the NY's avenues, running in the central park, and watching a Broadway's musical. I'm hopping to realize this dream.
