Cute 3D cartoon postcard with summer love mood

Create a vintage 3:4 postcard reminiscent of a "Love is..." gumball insert. Create a cartoon-style card with 3D stickers featuring a lens illusion, a light background, soft clay shadows, and sharp highlights, along with subsurface scattering. The image is reminiscent of magazine cartoons or stickers. The colors are rich and vibrant. The background is deliberately "cute." The main character is from a reference image, expressing emotion and mood. In the upper right corner are two red hearts and a daisy. At the top center is the title: "Summer is..." In the center is a 3D cartoon character. A tender, touching, and naive scene. Come up with a suitable background and design, clothing, and also add some humorous remarks in the form of comic-like speech bubbles, stickers, and brush-painted backgrounds with inscriptions in Russian, correctly written and easily readable
