This is the first time shooting action with a flash. It's more challenging than I thought lol. 1/200, F6.3, ISO 100 Shot with D90 and Sigma 24-70 2.8-4.0. SB 600 Camera right pointed up into subject. Shot at full power zoomed in to 70mm. Any critiques or advice would be greatly appreciated. I have many more but this one caught my attention as being the best.
