Double sleeve tattoo design in a surreal style, exploring the duality of good and evil. One arm features radiant, luminous patterns with intricate flowing shapes, soft glowing gradients, and harmonious geometric designs, while the other showcases sharp, angular lines, chaotic abstract forms, and bold, dark contrasts. The transition between the two arms creates a striking yet seamless visual balance. Avoid religious motifs or animal imagery, focusing instead on abstract and symbolic representations of opposites in a clean, highly detailed style.
