"Avoid incorporating features or elements that are not consistent with the Permian period or the nature of small predatory bony fish. Stay true to the proportions, body shape, and predatory characteristics of these fish from that era. Steer clear of unrealistic colors, patterns, or proportions that would compromise the photorealistic nature of the image. Exclude any modern or contemporary elements that may detract from the overall visual authenticity. Strive for accuracy and realism, presenting the fish in a photorealistic manner while capturing its predatory nature and maintaining the distinct characteristics of a Permian bony fish."
