You never did indicate the reason that Adobe gave you for rejecting the image, however I think that such images have limited commercial appeal, which could possibly why they were rejected.
We can't say until you share the full sized images. We have now asked you several times for the full sized images. Are you having a problem with providing them, for us to help you?
Although possible, I don't suspect the keywording or captioning was the reason for the refusal. Let's figure that out first and circle back to this if the assets are salvageable.
It would be helpful to list the refusal reason Adobe gave you as well as the same size files you sent to Adobe.
