Vibrant hand-illustrated birthday invitation card in a 5×7 portrait format, rendered in a polished flat vector illustration style with clean crisp ink edges and smooth screen-print flats. The composition features a lush, symmetrical floral border arrangement wrapping the outer edges of the card — dense clusters of open-faced blooms, rounded petals, and leafy sprigs in warm bubblegum pink, sunshine yellow, and fresh leaf green, with half-sliced citrus rounds (lemons and oranges rendered as cheerful flat graphic slices with visible segment details) tucked among the florals as accent motifs. Delicate looped satin ribbon bows in soft pink and yellow are nestled at the top center and bottom corners of the border, adding a celebratory, gift-like charm. The floral and citrus elements use bold outlined shapes with subtle inline highlight strokes and slight drop shadows to lift them off the surface. At the center of the card sits a clean, open arch shape — a graceful rounded gateway framed by a thin double-line border in soft gold-yellow — leaving the interior completely blank and unobstructed as a writable text area. The arch frame itself has a gentle hand-drawn wobble quality to feel warm and artisanal without being rough. No text, no filler, no pattern fills inside the arch. The overall palette is pink, yellow, and green with warm white used as fill highlights on petals and citrus rinds. The entire design sits on a single flat solid white background. Print finish is clean, smooth, and celebration-ready with no distressing. | PODspy AI Design
