Family postcard for May 9th

Retro poster in the style of Soviet painting: a warm family scene — a young man and woman in officer's greatcoats and side caps and children in soldier's uniforms sitting on a blanket in a blooming garden, smiling and hugging; St. George ribbons and red stars on their uniforms; the inscription "Happy Victory Day" prominently at the top in brush script; soft sunlight, golden-green tones, blooming apple trees and red carnations in the foreground; oil texture, visible brushstrokes, vintage paper texture, soft focus, warm nostalgic atmosphere, high resolution, portrait shot. Accurately convey the children's age. Without changing facial features.
