Festive Guitar Birthday Card

This design shows a rich marigold-yellow background that fills the whole card, setting a sunny party mood 🎉. Centred vertically is a classic six‑string instrument shown as a smooth, curving black silhouette, and the strong contrast makes it feel like a shared anthem between friends. The instrument is kept simple with no fine details, letting the shape carry the energy like a steady beat. Near the top, the message “IT’S YOUR BIRTHDAY!” sits in black, spaced clearly so it stands out against the yellow. Across the instrument’s body, “ROCK ON!” appears in white with a short dash underneath, like a quick note passed between close pals 🎁. A faint shadow falls to the right side of the black shape, giving it a little depth and a grounded, stage‑light look. The layout stays focused and uncluttered, keeping your eyes moving between the headline and the big central silhouette. The black instrument silhouette remains centred on the marigold field with its right-edge shadow slightly offset.
