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 final result must be 4k do not add any new objects keep the herringbone pattern exactly as is but increase the tonal variation between individual planks each stave should have a distinct natural shade ranging from light sand to muted beige change the surface to an ultramatte raw timber texture with visible open grain removing all artificial sheen or plastic like smoothness the goal is to see a clear organic contrast in color from one tile to the next emphasizing its wooden nature yet making the effect visible yet delicate and so it doesnt stand out too much the goal is for the change from the original to be subtle yet visible
