Generate an illustration of a mongoose and snake locked in a fierce, entangled battle, designed for an arm sleeve tattoo panel. The style should be a blend of new school and European-inspired neo-traditional, with intricate yet subtle ornamental elements. The composition should be vertically elongated to fit the length of the arm, making effective use of negative space to emphasize the movement and tension between the animals. The design should resemble a stencil, similar to an adult coloring book, with bold outlines and flowing details that will contour smoothly along the full arm. --niji 6
