A bold comic book-style graphic design with a black background featuring vibrant red and orange gradient bursts behind central elements. At the top, the word 'WARNING' is rendered in large, white sans-serif letters with a blue outline, followed by 'I'M A' in smaller white sans-serif text with blue outline, flanked by four white stars. Below this, 'GRUMPY' dominates in a large, gradient font transitioning from orange to yellow with a black outline, positioned centrally. Centered beneath the text is a hooded skeleton illustration with a black hood, gray beard, and glowing red eyes, rendered in a detailed, cartoonish style with visible shading. Surrounding the skeleton are three gray skulls (two larger on either side, one smaller below) and two yellow lightning bolts with orange highlights, all set against the red burst background. Below the skeleton, the phrase 'IF YOU DON'T WANT YOUR FEELINGS HURT' appears in white sans-serif text with a blue outline, followed by 'WALK AWAY' in a large gradient font matching 'GRUMPY' (orange to yellow with black outline). The design uses bold outlines, subtle shadows, and glowing effects on the text and skeleton to create a dynamic, edgy mood with a humorous warning tone, utilizing a high-contrast color palette of black, red, orange, yellow, white, and blue, with all elements arranged in a vertical composition emphasizing the central skeleton and text hierarchy.
