I Illustration is a branch of the arts that functions to convey messages or narratives. inthe present era, illustrations are often used as creative media that can be consumedand appreciated by a wide audience, motivating illustrators to continue producingwork. over time, technology has advanced rapidly, leading to the emergence of a formof artificial intelligence known as generative ai. generative ai is a technology capableof creating new content, including illustrations. this development has sparked debatesamong creative industry practitioners regarding ai-generated illustrations thatincreasingly resemble human-made works. the study of visual perception of generativeai illustrations aims to investigate the role of ai in the field of illustration from theperspective of creative workers and to assess the extent to which the quality of ai-generated illustrations has progressed compared to manually created illustrations.this research employs a descriptive quantitative method by analyzing responses fromparticipants who meet specific criteria using a likert scale, complemented byinterviews with manual illustrators and ai illustrators to support the data. the findingsobtained from questionnaires and literature studies indicate that ai-generatedillustrations still lack quality in terms of aesthetics and emotional expression, althoughthey are highly efficient in terms of production time. based on interviews andquestionnaire results, creating an illustration solely using ai is perceived as inferiorin aesthetic and technical aspects, and may also trigger the uncanny valleyphenomenon, in which viewers experience discomfort when encountering irregularitiesin ai-generated imagery. therefore, illustrators tend to prefer ai technologies thatguide or assist the creative process, rather than those that generate illustrationsindependently. in the creative process, maintaining a balance between human and airoles is essential to ensure the visual quality of the resulting illustrations.
