In the tattoo design, there are no unnatural elements. There should be no cartoonish characters, creatures with an unusual number of eyes, limbs, or other abnormal features. Fantastic or surreal elements are excluded, such as characters with disproportionate body parts, non-existent beings, or objects. The design must follow a realistic and natural aesthetic, avoiding the use of unnatural colors or shapes. Abstract or geometric patterns that disrupt the natural flow and harmony of the image are not permitted."
