ตัวอักษรลูกโป่งวันเกิด

Create a hyper-realistic 3D rendering of balloon letters forming the word [WOW]. Each letter should look like a shiny, inflatable mylar balloon with a bold printed pattern. Use a mix of textures such as [checkered print, color grids, polka dots, or glossy metallic black]. The balloons should be semi-reflective with realistic air volume, seams, wrinkles, and pressure points. Give each letter a distinct, playful surface design but keep the overall look cohesive. Use a soft pastel background, like [Orange color], to contrast the balloon textures. Lighting should create crisp reflections and soft shadows. The rendering must be photorealistic, fun, and vibrant — like a high-end visual for a creative pop-art birthday installation or fashion campaign.
