I think the histogram reveals a lot about the 3 photos that you've shared, they are all missing information on the whites portion and represents underexposure with the bulk of the information towards the blacks and shadows.
Photography is always at odds between technical perfection and artistic creativity and expression. With commercial stock photography the technical aspects are important because of all the potential ways it might be used.
The underexposure really shows itself when trying to raise the exposure until there is detail in the dark areas. I noticed very heavy banding and artifacting when attempting to do this with this photo. I don't think editing will save this unfortunately.
I hope you have better luck with future submissions 🙂
