3D Cartoon Father and Son Hug Event Poster

Full prompt

Father's Day summer event poster in a wide 16:9 landscape format. The backdrop depicts a sun-drenched day with a clear blue sky, fluffy white clouds, a golden sun, stylized cartoon cityscape buildings, and a vibrant yellow-to-blue gradient park setting. On the right, the main focal element is a pair of rounded 3D cartoon characters depicting a smiling father and son sharing a warm hug; the father wears a blue shirt and yellow scarf while the boy wears a matching blue cap. On the left, bold white typography reads 'Show Your Dad Power, Celebrate Summer' above the English subtitle 'Happy Father's Day', accompanied by three orange badges labeled 'Dad Challenge', 'Cool Dad Gear Station', and 'Photo Contest Prizes', alongside the event date '2026/06/21'. Bottom notes display registration reminders and handwritten script reading 'Time to Show That Real Dad Strength!'. Smooth, glossy 3D clay styling in fresh blue and yellow tones conveys an energetic, sun-filled family festival.
