It took me a while to find the right parts to make a Kid Flash that wasn't too bulky. I borrowed some parts (the sideparts from his head, the gloves) on the Young Justice Kid Flash.
Head and forearms : MU Johnny Storm, resculpted
Body : Yellow Jacket (wings cutted)
Lower legs : Deadpool
I used a coat of yellow paint with another coat of gold paint, so he's quite shiny.
For the rest, two shades of red did the job.
