While I think you have an interesting story, it is too hard to follow as you have written it. I have included your first page below:
Code:
1. EXT. STREET. EVE
Three friends walk side-by-side, through a rough, neglected
area. They are dressed in sports/urban clothing, appear to
be around 18-20 years old and are in good spirits. [color="red"]The boy
in the centre begins[/color] to tell a story to the others.
MICKEY
You know Keighley Thomas?
BEN
Yeah
TOM
Hayley’s sister?
MICKEY
Yeah. Well Harris fucked her the other day.
TOM
(Shocked) Fuck off!
BEN
That’s bullshit!
MICKEY
I swear to god. It was on Saturday at Tony’s party.
BEN
Says who? Fucking Harris!?
MICKEY
No, Keighley.
BEN
She actually said that? She doesn’t even deny it?
MICKEY
She can’t. Tony came down stairs and caught them at it.
TOM
Sorry, I’m not convinced that ugly-ass Harris could ever pull
Keighley Thomas.
MICKEY
Yeah, obviously that’s what everyone says when they hear it
but Tony saw them. Why would he lie?
...
There is way too much dialogue and not enough visual description of what is happening. Which boy is the
one in the middle-- Ben, Tom or Mickey? Why not just say
"Three friends, 18-20s dressed in sports/urban, walk side-by-side, through a rough, neglected
area. MICKEY, surrounded by his friends TOM and BEN, can't contain his news any longer."
Also, there is a lot of redundancy in the conversation. This violates an important principle of good script writing--avoid giving too much exposition. You want to be ruthless and cut it down to what's really important to the script. The important points are Keighley had sex with Harris. Get to the point. Also, break up the conversation with a bit of action so the audience/reader knows what happens between point A and point B. We are at page 3 when we find out that they enter the store. As a general guide, there should be some visual description after every 4-5 exchanges. It makes it far easier to understand what's happening.
And unless you're preparing a shooting script, you don't need to number your scenes.
Code:
EXT. URBAN STREET - NIGHT (CONTINUOUS)
Three friends, 18-20s dressed in sports/urban, walk side-by-side, through
a rough, neglected area. MICKEY, surrounded by his friends TOM and BEN,
can't contain his news any longer.
MICKEY
Harris got some at Tony's party. Keighley Thomas!
TOM
Fuck no! Hayley’s sister?
BEN
That’s bullshit! Says who? Fucking Harris!?
MICKEY
No, Keighley.
Ben stops and just stares at Mickey in disbelief.
BEN
I was at that party and those two didn't even make eye contact.
TOM
Sorry, I’m not convinced that ugly-ass Harris could ever pull
Keighley Thomas.
Mickey laughs and starts on towards the corner store. Ben and
Tom jog to catch up.
MICKEY
Tony said he caught them bollock naked doing the nasty.
BEN
Harris had all the coke. She looked pretty shit-faced anyway.
TOM
What’s the world coming to when somebody like Harris can
fuck somebody like Keighley Thomas?
Mickey opens the door and holds it as Tom and Ben enter.
BEN
Don’t knock it Tom. You might even be in with a chance now.
Tom gives Ben a playful punch to the chest. Mickey enters and the
door closes.
Unless the details of the blow-by-blow account are REALLY REALLY NECESSARY, keep it short and to the point. It's not important to direct the actions of the actors, but by adding some visual cues, it gives a sense of movement and can show rather than tell the audience/reader what is being felt.
In the slugline, I changed it to be more typical. The "(Continuous)" in this case means that they are moving. I don't need to specify all the details of the location. If I were moving about through a house, I might use continuous and just use the name of the room for reference.
Also, you need to focus on showing not, telling in your descriptions. Also break up distinct actions that might make a single shot. On page 4, you wrote:
"Without even communicating, the three friends run across the road and reign a fury of heavy blows in to the boy." Somehow they did communicate.
Code:
The boys glanced among themselves. Mickey begins heavy
footfalls towards the boy. Tom and Ben's face grow cold and
follow behind.
Mickey pushes the walking boy to the ground. Tom and Ben
run over as
the boy cringes and tries to protect himself from the rain of
blows and kicks from all sides.
As the reader/audience I am watching the scene unfold. If you intend to shoot the script yourself, it often helps to break out the shots. While this is typical of more recent action scripts, older scripts often have dense paragraphs. As a general guide, readers for agencies and production companies often prefer to see more white space on a page.
I think that the story pacing is a bit slow at first. It gets interesting when we start to meet Jimmy. But by that point, I've already started to wander a bit. I think fixing the dialogue and making it more visual will help to keep interest and move the story along to the real meat.
It shows promise. Good luck.
