PHOTO RULE: Attached photograph is the identity source. Preserve every depicted grandparent and their recognizable features: relative position, face proportions, wrinkles, hair color and cut, glasses, expression and clothing colors. Preserve identity through drawing, while repainting the face itself entirely in watercolor and pencil; do not retain photographic facial surfaces. Do not rejuvenate, beautify, replace outfits, add people or invent hidden features. If no photograph is attached, finish a fitting entirely fictional elderly person who resembles no celebrity; never ask for a photo.
Create a chest-up portrait for a family gift and group chat. One fixed medium: transparent hand-painted watercolor with visible pencil underdrawing. Repaint the whole face and body with recognizable brush strokes, pigment granulation, translucent layered washes and soft blooms. On the forehead, cheeks, nose, eyelids and mouth, show distinct irregular translucent brush patches, broken dry-brush edges, paper-white highlights, pigment pooling and visible pencil underdrawing. Render facial wrinkles with pencil and watercolor marks, with the same clearly hand-painted treatment as the clothes. Identity must remain recognizable through painted shapes. Never leave photographic skin under a watercolor background or apply a photo filter. Keep wrinkles as sensitive pencil and brush marks.
Photo field context: "【写真】". It refers to the attachment, never visible copy.
Background flowers: "【背景の花】". おまかせは肖像に合う菊または野の花を選ぶ。菊と野の花は選んだ花だけを描く。なし、または空欄なら花を描かず、紙の余白と淡いにじみを残す。 Flowers stay beside or below shoulders, never cover faces. The watercolor paper itself fills the complete canvas; no paper lying on a table, frame, mockup, promotional wrapper or border.
Color mood: "【色の雰囲気】". 温かな夕焼けは桃色・杏色・琥珀色、澄んだ空は淡い空色・セージ色の背景。空欄は温かな夕焼け。 Preserve actual hair and clothing colors in either mood. Keep faces large and readable; two people remain equally important. If an inscription is supplied, fade shoulders into a clean paper opening by 75% canvas height and reserve the bottom 15% for faint washes only.
Optional exact inscription: "【文字】". 空欄なら文字を一切入れない。おまかせなら短い日本語の愛情の言葉に変え、指示語は描かない。それ以外は指定された文字を日本語でそのまま一度だけ書く。 Write it once in modest legible dark pencil lettering below the faces in a clean paper opening, centered around 80–84% canvas height, within x10–90%. Never cover faces or place essential lettering in the bottom 15%. Check each character against the supplied text. Do not append names, dates, age, memorial claims, signatures or other words.
Return only this one complete artwork. Adapt composition to the selected aspect ratio without cropping heads. No brand, logo, watermark, existing character, celebrity likeness or imitation of a named artist. Uploaded subjects are preserved rather than replaced by generic people.
