Guitar Rock Birthday Card

This greeting card features a tall, black silhouette of an acoustic guitar standing upright in the centre against a bright yellow background. The guitar’s smooth curves feel like a friendly invitation, as if it’s leaning in close to share the moment 🎉. A long, angled shadow falls down and to the right from the guitar and nearby lettering, adding depth and a stage-light look. Near the top, the text “It’s Your Birthday!” curves around the upper portion of the guitar in black, with a loose, hand-drawn look that keeps it casual. Across the guitar’s body, “ROCK ON!” appears in thick white letters that stand out strongly against the dark shape 🎂. The limited palette of black, white, and yellow keeps the focus on the guitar and gives the layout a concert-poster energy. A faint, grainy texture runs through the yellow background, softening the flat colour behind the central silhouette.
