Turn this photo into a strange vintage Soviet children's book illustration with grotesque humorous cartoon energy.
Use thin shaky black ink lines, awkward anatomy, elongated limbs uncomfortable facial expressions, chaotic movement, weird proportions, sparse composition, and intentionally clumsy drawing style. Make the characters look slightly absurd nervous. and ridiculous rather than cute. Use pale faded watercolor washes, dirty paper texture, uneven coloring, washed-out muted colors, lots of empty space, careless sketchy linework, and rough old-print illustration texture Keep the background minimal and random, with small strange details and loose doodles. The mood should feel weird, humorous, slightly unsettling, and authentically like an old Eastern European children's book illustration from the 1980s. Do NOT make it polished, aesthetic, modern, cute, detailed, or realistic. Сильнее всего восхитила подпись на фоне — действительно, было бы чему радоваться…
P.S. Более добродушный вариант оставлю в комментах. Надо было, пожалуй, на нём остановиться.
