I would like to know if something is missing for the relief here I leave an example
From a modeling standpoint, that looks very simple and easy to make. It doesn’t impress me personally because it looks like you just slapped a material on it and rendered it. It might look better to others who don’t have any experience. Also, It seems very plain. Add at least a gradient background (Slight fade from gray at bottom to white that is barely noticeable) or some text because I don’t understand the goal of this render.
From what I saw of your other posts, your knowledge of nodes is improving. This is good in terms of a material, although personally the displacement/bump you’ve added is too sharp.
You should try adding something like this into a scene, say as a statue or something. That way you can get experience in integrating lighting, materials and scene composition into one picture.
He just got into cycles and is working on improving his knowledge of nodes to achieve realism.
