I'm not an expert like many of the guys on here but for what its worth, here is my feedback - You mention "body" twice in the first sentence, delete one of the references. Your descriptions are trying to be evocative but I would suggest you say more with less. Keep it concise. Also, you cannot describe things the audience cannot see, an example is "unaware that the bus has already turned the corner". To describe this I would describe the action first, then the result. for example: the bus departs around the corner, the school girl arrives at the bus stop, looking around.
On other thing I notices is the use of "CONTINUOUS" in the slugline after the FRONT YARD scene. It cannot be considered "continuous" when James is in the the yard and in the next scene he is sat inside, it is a new scene. CONTINUOUS implies the action moves from one location to the next in the same beat.
Overall, I think the script gets better as it goes on, it's hard to judge without the context of the full story, but it's certainly not bad. I like some of the casual dialogue, and it seems like the story is setting up for something better. Keep going with it, would like to hear the next stage of the story!
