Avoid ordinary and clichéd illustrations. Discard artworks with blurry, distorted, or poorly drawn elements, as well as those of low-quality standards. Ensure that the eyes are not crossed-eyed. Steer clear of cartoons or misaligned texts that detract from the overall quality. Reject pieces with multiple flaws, such as extra limbs, deformed hands, or awkward proportions. Instead, embrace the beauty of well-executed, highly detailed illustrations that impeccably capture the essence of Luna's celestial features and the enchanting Space-themed ambiance.
