八一建军节红色大气年会盛典海报背景

A red gradient background with light blue and orange color waves, featuring an abstract city skyline in the bottom right corner. The buildings have sharp edges and appear to be made of glass or plastic material. There is a large white space at the top left that can serve as a banner for text or other elements. This design would work well on digital media like website banners or social media posts. It has clean lines and a modern aesthetic.
