Create an image that captures the concept of 'Happiness' by using appealing techniques associated with the vaporwave aesthetic – pastel colors, 80s and 90s nostalgia, Greek busts, glitch art, and tropical scenery. The image should be a collage, showcasing different elements that represent joy and contentment, such as sunshine, laughter, music, friends, healthy food, nature and hobbies. Each of these elements should be artfully arranged to create a harmonious composition that communicates an overall sense of happiness.
