head at 60-degrees with white-card extended.
Was that bouncing off the ceiling then? Or just using your white card as a reflector to broaden the light source?
If it was off the ceiling, I'm surprised it didn't illuminate more of the background. The best results I've had have been bouncing off the ceiling (when it's low/light colored enough) but then also using a little white note card to reflect some of the light directly forward to fill in the shadows/eye sockets.
Anyway I mention that because I just notice the backgrounds going near-black. Could always try 1/30th sec to pick up a little more ambient light if bouncing the flash won't work.
