Full-color tattoo sleeve design for forearm, Japanese-style dragon wrapping around the arm. On the outer side: a central half-heart, half-mechanical engine shape, with the dragon’s tail coiling around it. On the opposite side of the arm: the dragon’s head in traditional Japanese style, fierce expression, long whiskers, vibrant scales, horns, and flowing mane. Dragon’s body connects between the two sides, with smooth flow and balanced composition. Designed for a tattoo, clean bold outlines, skin-safe shading, vivid colors.
