Super nice shot here! You've put a lot into it. I've got a question on the lighting aspect. With a flash, you're probably limited to a 1/250 shutter (or possibly 1/320 with hi-speed sync on some cameras - unless you're shooting with an electronic shutter but I doubt that). That's not fast enough to really freeze the action of course, although at this distance the angular speed of the subject is reduced, even though he's hauling the mail here. Does that mean it's really the flash freezing the action? (the flash burst is much shorter than 1/250 typically). In other words, you're getting a reasonably sharp rider here because although the shutter is open for 1/250 sec, the ambient light it's receiving during this time is so much weaker than the flash pulse, that the motion blur part of the exposure "disappears"?
I've been meaning to get into off camera flash photography, this is one aspect I've been wondering about.
Oh and just to point out, I know the reason for the shutter speed limit, with a dual curtain shutter like on most DSLRs at shutter speeds faster than 1/250, the rear curtain starts closing before the 1st curtain has finished opening completely, so any flash that fires during this time could never expose the whole sensor - so you'd end up with part of the picture lit with flash, the remainder unlit. I know that part.

Sick shot dude! Nice lines and lighting!
