So, as it is now, I’m rating it three stars. Not because it’s bad, but because it has potential to be better.
First: The characterization is a bit shallow. First person stories allow for an exploration of the inner psyche that third person stories lack. You want to use this advantage and really get inside your character’s head. People don’t view the world in objective terms, but rather are constantly making subjective observations about the things around us.
For example, I didn’t just see the group standing behind the store. I stared as the group skulked behind the store like an ominous clot, eying passersby and talking in hushed, quick tones that no doubt betrayed unsavory intentions.
You see the difference? By displaying the assumptions and prejudices of the character through the writing, we can begin to triangulate what sort of person they really are. Don’t just tell us what’s happening, show us how the main character perceives what is happening. This is especially useful when we haven’t been given any character description, because readers will assume things about a character’s appearance by the nature of their actions. It’s strange, but true.
Second: A few grammar inconsistencies. You need to maintain your tense. The very first sentence is in past tense, but the rest of the story is in present tense until they cross the street, at which point it reverts back to past tense. Choose one or the other and stick with it and your readers will be much less confused.
Third: Certain sentences would be better separated, rather than linked by commas. Also, you only need to tell the reader that the character is late one time, either in the narrative or through the dialog. Any more is redundant.
I think this could shape up really nicely. Keep it up.
memento, Wow, I appreciate all the advice you’ve given me! & I seriously appreciate that this can be helped further. I’ll do some work on it soon for sure, so please check back in with it sometime so that you can see if it’s improved?
