The script of my preliminary task

I am writing my script for my preliminary task. This is a plot for a film noir. And here is a part of my script:

And I also analyse it:(as shown below)

When I am writing the script, I find that it is not really easy. First, I don't really know about the format, and I write in the wrong format. Therefore, I have to rewrite it. And I have to think about the story. Every time I think, I get a new idea, that makes me change the description of the scene and the dialogue. I and Melissa are doing together, so we discuss the script a lot. I hope I can write a better one after discussing with Melissa.
