Create a graffiti style artwork that depicts the vast expanse of the galaxy, featuring celestial bodies such as stars, planets, and nebulas. Incorporate bright, bold colors to represent the energy and vitality of the universe, and use sharp, angular lines to convey a sense of movement and dynamism. Consider including elements of street art, such as tags or stencils, to give the piece a raw, edgy feel. You could also experiment with layering different textures and patterns to add depth and complexity to the piece, creating a sense of depth and dimensionality that draws the viewer into the cosmic landscape
