Elegant Sketch Birthday Card

Designed with a monochrome, pencil-style look, the front shows three round balloons floating up from an open gift box, their soft shading giving them a gentle sheen. Thin strings trail down from each balloon and meet neatly at the box, like they’re gathered together in a close, affectionate bundle 🎉. The box is drawn with fine cross-hatching for texture, and a ribbon wraps around it with a bow sitting on top. A small shadow sits beneath the box to keep the scene grounded, while tiny scattered marks around the balloons suggest light confetti drifting in the air 🎁. The mood reads like quiet friendship, with the balloons leaning slightly toward one another as if sharing the moment. To the right side, the words “Happy Birthday” are placed in dark lettering with smooth, flowing strokes that echo the curve of the balloons. The background stays plain and bright, letting the black-and-white lines, confetti specks, and ribbon details stand out.
