Simon,
OK, that's exactly what I thought you were aiming for, and achieving, but of course it never hurts to ask, does it?
Next time, just to keep me happy, once you've done the shot that you want, pop the flash up, dial it down to -2 and -3, and shoot one of each with only the addition of that little bit of fill.
IO think the results could be very nice.
Or I could be totally wrong, but there's only one way to know for sure.
