puede aclararme o guiarme, para saber por qué se rechazó la foto, cuáles son las fallas, etc.
Hallo, I'm not sure what the comercial value is but your photo is not in focus.
Out of focus and hazy, lacking contrast; probably because you shot on a sunny day and with a shutter speed too slow to capture the surface of the water while it was moving.
You should always post with the picture the reason Adobe gave you for the refusal.
@Ralph Lear: the commercial value of such a picture may be the use as a texture. But as you pointed out, it is out of focus.
No need to try to correct the missing contrast and the exposure, out of focus is not correctable.
