This is quite good. I love the flash you've put in here. Radio slaves work wonders for action sports like skateboarding. Nice job and great capture.
Were you going for the background siloulette? Leaving the shutter open a little longer might guve us a glimpse of the ramp and the opportunity to see just how high he might be over that ramp. a 4 foot miniramp versus a 12-13 foot vert tamp makes a big difference in this great backside indy.
