Smile Big design T-Shirt

A vibrant and playful illustration of a kid-friendly design on a white or light-coloured T-shirt, featuring a whimsical scene with cartoon-like elements, bold lines, and bright colours such as blues, greens, and yellows, with subtle textures to give it a soft, fabric-like appearance, the design taking up most of the shirt's surface, with a clear focal point, possibly a smiling cartoon animal or a fun graphic, surrounded by curvy patterns, stars, or bubbles, with a clean and simple typography, sans-serif font, in white or a contrasting colour, with a few words or a phrase, such as "Smile Big" or "Be Kind", in a playful, cursive script, and a few subtle shadows to give the design some depth, all elements carefully balanced and arranged to create a visually appealing composition that would appeal to children.
