They must be totally flat photos. The exposure is something that everyone uses to their liking, so, what photo and how can they be loaded or be commercial moivo?

What bis a flat photo? I understand enough Spanish to read your remark in Spanish, but I do not understand what you mean with that.

The exposure is not something that you like or not, it's based on the histogram of the picture. The histogram needs to cover the whole spectrum, but there should be no clippings at the ends. But to be clear, you can do selective exposure adjustments in your pictures to enhance the overall apearance of a picture. That is part of the preprocessing steps that you should do, before submitting. And that is also part of what has been done during all the times that photography exists. 

The same with the composition. There are theories about how the human brain processes visual information and based on those theories there is a guide about how composition has to be. It's, however, astonishing (or not that much astonishing) that the old masters did exactly follow those composition rules in their paintings. 

Commercial appeal is based on Adobe's experience on how the assets sell. In your case, the dove, the towel and the tight cut make this asset unattractive and the overall impression is that it would be difficult to sell. But that should not discourage you, I have assets in my portfolio that do not have a high commercial appeal but do sell in low numbers. 

Read the Adobe Stock Learn & Support Help pages, which contain a lot of information about Adobe's requirements. This will help you to understand what they consider to be of commercial appeal.
