I can understand your desire to get a definitive answer here, but I think it may not be possible.
As I see it, your photo takes us into an area of the A.net criteria where there is a significant degree of subjectivity. My own hunch would be that some screeners would interpret the motive 'rules' as I did, and consider that it may not be 'safe' enough to pass. Others may feel, as some do here, that they like the crop and the motive. I would have to agree that, overall, the first crop has something on the second - I would just be unsure about it myself.
It must be hard for a screener to say publicly what they think here, when they may well know that not all their colleagues would necessarily come to the same conclusion. That would just leave them open to criticisms around inconsistency. I think that is the dilemma many experienced uploaders have confronted at times when dealing with subjective elements to criteria. Like it or not, the only way to know the outcome is to upload and take the risk, and make use of the appeal function when you feel that is appropriate. For what it is worth, I would be confident that 'motive' would be the only reason for it not being accepted - everything else is very good.
Whatever you decide, good luck. I think we all have some responsibility to think of novel motives, new angles, different viewpoints etc to keep the database as interesting to viewers as it can be.
All the best.
