My personal attempt somewhere attached to this message.
I would be very wary in judging a film when there are so many variables involved:
- monitor calibration differences;
I also see a greenish cast in the picture as posted by the original poster. A little bit of this greenish cast on the parapet is probably due to the greenish reflection of the pond, so I did not eliminate it completely so as to avoid a magentaish cast emerging.
The sRGB colour space is in any case inadequate to render the amplitude of the palette of a colour film.
The scanning sacrifices highlights and shadows, burning the former, blocking the latter. It should be very easy for a scanner to capture the entire dynamic range of a negative colour shot. The contrast is then recreated by applying gamma curves while keeping the extremes safe. This looks like the scan of a slide (and that can be improved as well).
The colours seem to be fine although, not being there, I cannot judge on the rendition of the correct hue of the flowers. I don't see any colour problem besides the difficulty in filtering which is somehow intrinsic in the use of negative colour film unless a proper colour-managed workflow is adopted.
