I love that shot, and it's so sharp it looks great enlarged. But is there a chance you scanned it backwards?
I've always liked Portra for its subtle colors over some of the punchier, more saturated color films. But then, I like color shot on good, single coated glass too. I had some Hasselblad lenses from the early fifties years ago, Zeiss glass with no mechanical coupling between the lens and camera. The rendering was gorgeous. That lens with VPS, the precusor to Portra, was color perfection to my tastes.
