This scene is lit by 2 strobes and the ambient light from the overhead lanterns.
First, I had to establish the ambient light to burn in the lanterns which was around ISO 1250, f7, 1/15.
Next step was to cross light 2 strobes set at around 1/16 power. The flash freezes the subjects instantly while the slow shutter speed allows the lantern and the light from the shed to burn in.
The image below uses the same lighting setup with the added touch of sparklers.
