Retro Americana Skinny Tumbler Wrap

Design a seamless 20oz skinny tumbler wrap illustration edge to edge, 2790 x 2460 px, filling the entire wrap edge-to-edge across all three panels — not a centered vignette with empty background. Style: retro Americana meets modern preppy/coastal-grandmother, hand-illustrated with clean linework and soft shading, not flat vector. Background: soft pastel candy stripes (blush pink, sage green, cream, dusty blue) running the full length of the wrap, with a few small gold stars and delicate ribbon flourishes scattered throughout — not overcrowded. Centerpiece: one mallard duck in mid-flight, wings partially extended, positioned to flow naturally across the panel breaks, wearing a small wildflower crown and a blue ribbon bow at the neck (not pink). Include one small duckling tucked into a cluster of wildflowers and cattails at the base, plus one tiny mushroom accent nestled in the greenery. Add a curved banner or ribbon scroll with the word 'LUCKY' in bold vintage script or serif lettering as a secondary focal point, styled like a badge or ribbon banner rather than plastered text. Include a few small delicate sparkle or rhinestone-style glint accents near the stars for a subtle glam touch. Color palette: dusty pink, sage green, cream, soft gold, muted blue. Leave clean negative space along the top and bottom edges so nothing is cropped once wrapped around the cylinder. Avoid a centered single-vignette layout, avoid leaving large empty background zones, avoid text baked in anywhere except the 'LUCKY' banner.
