Follow the sequence
Mark the first hint of trouble and the moment it becomes clear. Check what changes between those points: framing, sound, scale, or a character's expression. These choices organise the reader's attention.
Look at quiet panels
A still room or empty corridor can hold the reader between events. Ask what information the panel provides and which questions it leaves open. Silence needs structure to feel purposeful.
Study restraint
Compare a fully explained threat with an image that leaves part of it outside the frame. Consider which version supports the story's tone without assuming that more visible detail creates a stronger effect.
