Vertical black and grey tattoo design featuring a composition of delicate flowers intertwined with butterflies. The flowers should be detailed with intricate petals, creating a sense of softness and elegance. The butterflies, in various sizes, should be realistically shaded, some perched on the flowers and others in flight, adding movement to the design. Fine linework and shading should create strong contrasts, enhancing the depth and texture of both the flowers and butterflies, giving the overall design a serene yet dynamic feel.
