Like Latin Lens said, It would have more powerful to focus on one child for your character and it would have made it easier to sequence out. Does your station have rules against showing the whole graffiti tags or were they vulgar because I would have liked to see a wide of a covered wall or something don't get me wrong I Like the tights too but without variation it lost impact. Since this is a Sweeps piece you get to really develop your story so....
This is one it could have been cool to start out side of the gym in the streets with a line like "these streets have been plagued with violence for years and children struggle with it every day....... and show the gang tags on walls maybe shoes hanging from power lines, boarded windows, beer bottles anything that indicates the type of neighborhood it is. Then a quick byte from the kid outside walking to the gym THEN reveal the gym and the hope it provides and how it helps this kid specifically. End with kid packing up and leaving the gym to goes into the streets again.
Over all strong shooting it just didn't have that "little extra".
