take this semi final render and enhance realism without altering any of the current image s geometry features or objects as well as image orientation no cropping zooming etc and make it 4k do not add any new objects that includes materiality structure etc for example the sunbeds that extend to the water have a black marble like built in structure follows the depth of the pool that must not change or be reinterpreted as other material the goal is to have a realistic facade render enhancing contrast and existing textures as for the lighting it must be as is but the colors should emphasize realism as natural light has its effects on materials as for the colors we re aiming to brighten up the composition making the colors more vivid without forcing realism the plastic effect output must be a professional architectural visualization in high resolution 4k
