Prompt
Physically based 3D render of matte rubber balloons arranged in a vertical 2:3 card layout. The characters 'X', 'O', 'X', 'O' are stacked in pairs, with the soft-textured pink and crimson balloons leaning into each other as if embracing. The material has a premium matte rubber finish with subtle subsurface scattering. Warm directional lighting emphasizes the soft curves and physical contact between the balloon letters. The composition is intimate and cute, designed for mobile screen backgrounds. The background is a clean, complementary pastel gradient.
