I chose a much more challenging background, but the result is much the same.

 

Exposing for the bright sun outdoors, my shutter speed had to be pushed to 1/500, stopped down to f/9. SB-900 fired CLS / TTL, which figured out how much strobe it needed. Strobe fired through my trusty Lastolite tri-grip, up and left-- slightly forward. This actually pushes the strobe, technically, into high speed sync.

 

An interesting change-up that worked out.
