What significant challenges do artists encounter when attempting to create a convincing mimic comic?

Artists face several significant challenges. The foremost is the immense difficulty of perfectly replicating another artist's unique 'hand' or style, which is often the result of years of individual development. Achieving consistent mimicry across an entire comic, maintaining the delicate balance between homage and outright plagiarism, and ensuring the new content stands on its own while deeply rooted in the original's aesthetic are substantial hurdles. Additionally, navigating legal issues related to copyright and intellectual property, especially if the mimicry extends beyond non-commercial fan art, presents a complex challenge.
