Bob,
This is an outstanding exposure. I am surprised at how much grain you seem to have. My preference is for the Portra 160 films which don't appear as grainy. I was not familiar with VPL, can you explain a little more about the film?
I am aware from experience that a digital scan of a negative with perceptible grain will emphasize the graininess, depending upon the pixel size. This may account for what is being exhibited in you digital image. What size is your largest print where the grain is acceptable?
