My daughter and I were just discussing this the other day. I was catching her up on the progress of my book and telling her I was concerned because the chapters are quite short. I tend to write tightly. I'm concise and don't add anything I don't think is absolutely necessary to the story. Adjectives and adverbs are scarce. When (if) it gets to an editor, I may find myself searching for more to say about the topic, however, for now, it's short.
My daughter advised me not to worry too much about it. As she said, "It's much easier to add than to cut what you've worked hard to write." True dat.
