Create a detailed sketch of a snake tattoo. The design should feature a coiled snake with intricate scales and a dynamic, flowing pose. Emphasize the snake's head with a slightly menacing expression, its forked tongue flicking out. Include subtle shading to highlight the texture of the scales and give the design a sense of depth. The overall style should be clean and bold, suitable for a tattoo, with a focus on both artistic and anatomical accuracy. Consider incorporating elements like floral or geometric patterns in the background to complement the snake tattoo idea
