I think you misunderstood my comment.
The subjects are interesting, the composition is good, the framing is good, the whole artistic component is good. 😀

I was referring only to the vertical alignment of the elements corresponding to each pair of images (when mounting stereograms).
An incorrect alignment produces a visual discomfort proportional to the alignment error and the size of the image when viewed. I look at images on a medium size 4k screen (55") and the misalignment is immediately noticeable.
It was not easy to correct the anaglyph in the absence of the original images, but I tried to show you what it is about in a direct comparison.😀

The yellow bars reflect the intensity of the misalignment of two identical elements in the image pair. They should be closer to the horizontal position.

I hope you're not upset. 🙏

Not upset at all and no offence taken. I am trying to learn more about phantograms, which I have only just come across, and criticism is very welcome.

I get what you refer to now. My problem is that with phantograms, as opposed to plain 3D, moving the left image vertically vs. right also moves the zero displacement level as well. That zero displacement level should also have no vertical discrepancy (or horizontal) and improvement of the closest part of the subject may be a compromise with the furthest.

Thank you for your input.
