The point is both scenes and chapters have a place in your story’s pacing. Short chapters tend to move the action along quicker. Longer chapters might lull you into relaxing with the longer flow of information and less tension. Remember, both scenes and chapters have a part in how quickly your story unfolds, and how your reader experiences the story.
How has your protagonist or hero changed since the beginning of the book? Think through who that character was at the beginning of the story, consider the journey and the challenges, and the impact on him or her. This is subtle or may be dramatic, but if there are no changes to the characters, the story is really a linking of scenes in which pretty boring people get up in the morning, do stuff, and go to bed at night, no different.
