What are the technical challenges involved in creating a compelling silent horror comic without relying on text?

The technical challenges are significant. Without text, creators must ensure that every visual element—character expressions, body language, background details, object placement, panel transitions, and color palette—is perfectly clear in conveying emotion, plot progression, and the intended horror. Ambiguity must be controlled to enhance dread, not confusion. Maintaining a consistent narrative flow and ensuring the reader understands 'what happens next' solely through images requires meticulous planning, strong artistic skill, and a deep understanding of visual storytelling principles.
