There are some formatting errors, corrected below:
INT. ANGELíS APARTMENT BATHROOM - DAY
A plush bachelorette pad located in the small sleepy town of Summerville, SC.
ANGEL, early twenties, a red-boned dancer with a toned physique, flawless skin and natural curls, stands in the bathroom mirror in a worn pair of faded Tommy Hilfiger jeans, a red crochet tam, and a plain black tank top applying last minute touches to her hair and makeup.
She impatiently fusses with her bangs for several seconds, then abruptly decides to ditch the hat and tosses it to the floor as she makes a hasty exit.
EXT. TRAFFIC INTERSECTION - DAY
Angel comes to a stop at the red light. A small staple of motionless pine trees on the side of the road catches her attention.
She quickly surveys her surroundings to make sure no oneís watching then returns to focusing on the still branches of the pine trees.
(whispers to pines)
Stop... go... stop... go...
EXT. ANGELíS GRANDPARENTíS HOME - DAY - (FLASHBACK 1981)
A strong steady gust of wind ripples through the pines of a nearby field as a young Angel looks on in amazement from the porch steps.
Abruptly, the wind stops.
Within seconds, the strong breeze returns as the giddy nine year old continues repeating these commands at different intervals.
I took the liberty of correcting misspelled words and formatting errors.
When characters are first introduced in the script, their names must be in all CAPS.FADE IN:
has fallen from fashion and there is no such thing as FADE IN ON:
Also, I do not recommend using FLASHBACK TO:
as there is no such transition, at least officially. Technically, it's not incorrect to use FLASHBACK TO:
, but I have never seen it used in a script ... and I've read quite a few. The most common form is the one you see here.
The only other thing I noticed was that you have placed your character at her grandparent's home, but there's no description of the house at all ... it it urban? A remote farm house on the Kansas prairie? In Miami?
