I found a common error on your text: confusion between possessive pronouns and verb to be.
The correct writing is the following
| Verb ToBe versus Possessive Pronouns | ||
|---|---|---|
| Subject | To Be | Possessive Pronoun |
| I | am = I'am | mine |
| You | are = you're | your |
| He | is = he's | his |
| She | is = she's | her |
| It | is = it's | its |
| We | are = we're | our |
| You | are = you're | your |
| They | they = they're | their |
For example, lets correct the following sentence in your text:
"... the huling shadow appeared in the broad streets taking theyre bullets"
Correct form would be
"... the hulling shadow appeared in the broad streets taking their bullets"
You had a few typos as well, you only need a second read and revision. Nothing really bad.
