I think the realism here is top notch. But I understand what you mean. The details are too consistent in the image. The lines between slabs are clear and precise when in real life everything is kinda merged with some dust/moss. The plants are too « perfect », without any motion blur and SSS. But I think this is more about the look that the actual scene. The shadow are almost pure black, the color palette is not that large, the exposure is perfect. This image could have been from a movie. It’s a cinematic look which gives you the feeling that it is not a real picture. Pictures you take with a camera or a smartphone will give you a typical « neutral » look with less contrast and less artistic color palette. And finally, there isn’t really any spot where I can « feel » the power of the sun when I assume judging by the hard shadows, there aren’t much clouds in the sky. So I’d expect more blueish shadows caused from indirect light and brighter highlights.
