Crisp vibrant vector illustration of a skeleton witch riding a mummy T-Rex, rendered with strong clean black outlines, bold cel-shaded flat fills, and sharp highlight accents throughout — isolated on a solid flat black background with no texture, pattern, or gradient behind the subject. The mummy T-Rex dominates the lower two-thirds of the composition, massive and side-angled with a slight three-quarter turn toward the viewer — its large scaly body rendered in deep swampy green with flat shadow planes, wrapped in aged off-white and cream bandages layered across its torso, neck, head, and tail with frayed trailing ends, bold black outline stitching details on each wrap. Its jaws are thrown open wide revealing rows of sharp white teeth with a deep magenta-black mouth interior, and its intense amber eyes glow with a warm golden ring against dark pupils. In its stubby front claw it grips a classic orange Jack-o'-lantern trick-or-treat bucket overflowing with bright candy — lollipops in red and white swirl, striped candy canes, wrapped candies in purple and yellow, spilling slightly over the rim in a playful cascade. Perched confidently on the T-Rex's back is a grinning skeleton witch — clean white bone anatomy with bold black outlines, hollow eye sockets radiating a vivid electric green glow, wearing a tall pointed witch hat in flat black with a deep purple band and a small gold buckle accent. A tattered black cape fans dramatically behind the skeleton fastened at the collar with a tiny bat-shaped clasp in dark pewter. In one bony hand it raises a lit brass lantern with a carved jack-o'-lantern face panel — warm orange candlelight glowing from within casting a subtle orange halo on the surrounding bones and hat brim, rendered as clean flat vector glow without bleeding into the background. Composition reads as a dynamic side-profile parade pose with strong left-to-right momentum — T-Rex mid-stride with one foot lifted, tail arcing right, candy bucket arm extended forward, skeleton rider leaning slightly back with cape billowing and lantern raised high creating a strong vertical accent at the top of the frame. Color palette: deep swamp green, aged off-white, flat black, rich purple, warm amber-orange, electric green eye glow, brass gold, bright candy accent reds and whites. Illustration technique: clean vector paths, bold uniform black outlines, flat ink shapes with deliberate cel-shading shadow planes, no gradients, no halftone, no distress — crisp screen-print-ready linework throughout. Solid flat black background. | PODspy AI Design
