Preston,
I know that spot (see) and I know the look of that film! I miss Astia, with its muddy brown shadows and low contrast. It made it easy to scan and then had the latitude needed for editing.
If this was mine, I would lower the reds in the shadows a bit and then maybe bump the overall contrast just a bit. Here is what I think.
The adjustments are subtle.
The reflection in the water and the subtle blurred leaves on the right really give the sense of calm and quiet.
