Vintage Roaring Tiger Japanese Poster

Create a bold vintage Japanese-inspired poster on a square canvas with a fierce front-facing tiger head as the single central subject, perfectly symmetrical and filling most of the frame. The tiger is roaring with its mouth wide open, showing long curved ivory fangs, smaller lower teeth, a vivid pink tongue, a dark throat, a pink nose, intense yellow eyes, and dramatic black stripes over saturated orange fur with white cheek and neck fur. Add ornamental swirling stripe patterns on the forehead to give the face a stylized mythic look. Use a gritty retro screenprint or risograph texture with visible grain, worn ink, slightly distressed edges, and a limited palette of burnt orange, black, cream, white, muted pink, and small accents of yellow. The background should be a flat textured orange-red field. In the top right, include 1 small technical diagram panel showing a side-view tiger skeleton in thin cream line art with compact vertical Japanese annotation text beneath and beside it, like a pseudo-scientific label block. In the bottom left, include 3 vertically stacked icon boxes with thin cream borders: the first contains a heart icon with the label 心, the second contains crossed bones with the label 力, and the third contains three claw marks with the label 本能. Across the bottom center, place 2 very large cream-colored Japanese kanji characters with heavy black drop shadows and a rough hand-cut block print feel: 猛獣. Keep the overall composition aggressive, iconic, poster-like, centered, and highly graphic, blending traditional Japanese poster aesthetics, tattoo flash energy, and vintage animal anatomy chart styling.
