Here is the reference photo, which I tried to replicate as closely as I could (imo, the best way to learn photorealism is to mimic real photos and scenes). https://cdn.fredericia.com/Perfion/Image.aspx?id=21635c08-ac4d-4a4b-a23c-598361cf138e
Everything was modeled from scratch in Blender, except for some of the plants and flowers (I found some here and there, especially from 3dsky and 3dbrute). I modeled the eryngium and the green-white oregano type plant myself.
As for the rest, the final resolution is slightly lower than the original photo. I used 2000 samples and denoising via the compositor node.
C 'n C always welcome.
PS The render with the original resolution is here
