No one is lecturing you, I just mentioned of how unpractical it is to have someone read your stuff to interpret your vision instead of going straight to the point and just let them know what it is they have to do.
Reading a 10 page character bio o having to read a novel in order to draw two characters interacting in a cover it just sounds like an excuse to try to gain a free reader more than having the actual resources of what elements to draw.
If you have experience, ok, your main thread without editing just sounded like an overly excited person that was being way too vague, and not very different from first time commissioners who would dump a lot of unnecessary information to an artist when what they want can be expressed in a sentence or two.
