Vertical Vietnamese greeting card in soft watercolor style on textured off-white paper, vertical aspect ratio suitable for mobile messaging. In the lower corner rests a neat stack of Vietnamese-style school notebooks with grid-lined pages, a fountain pen, a red pen, and a lovely bouquet of pink carnations, yellow chrysanthemums, and delicate baby's breath tied with a satin ribbon. The upper half is an open, clean, empty cream-colored watercolor wash background leaving generous blank negative space for custom text. Centered elegantly above the flowers is the headline: "Chúc mừng 20/11" in graceful calligraphic brush lettering (the quotation marks themselves are not drawn). Warm soft morning window light, pastel tones of peach, pale green, and cream, family-friendly, peaceful teacher appreciation theme, no people, no other letters, words, or numbers anywhere.
