Handmade Editorial Couple Illustration on Textured Paper with Minimal Acrylic Aesthetic

Create a refined handmade editorial illustration based on the reference photograph, preserving the couple’s recognizable appearance, natural proportions, affectionate embrace, expressions, and clothing. Present the artwork on a tall portrait smartphone-wallpaper canvas with warm off-white textured paper. The couple forms a compact, moderately sized central illustration, positioned precisely around the geometric center of the full canvas, with balanced open paper space surrounding the artwork on every side. The composition should have a calm, elegant wallpaper layout, with the couple clearly centered rather than filling the page. Use delicate imperfect ink lines, simplified acrylic-style color shapes, visible brush texture, softly irregular edges, and subtle handmade imperfections. Preserve the original color character with a restrained palette of four harmonious tones. The final result should feel like a minimal premium handmade phone wallpaper—a small-to-medium centered couple portrait on a full tall paper canvas, with generous but naturally balanced negative space around it. Face same as reference image. Ratio 9:16. Insert discreet watermark in the lower right corner of the image, vertical text (rotated 90°), written "aipromptlabs.online", Calibri Light font, white color with low opacity (semi-transparent), medium size. Extreme sharpness on the face, fabric texture and typography of the letters. Shot on Canon EOS R5, 50mm f/2.8, studio light.
