• Super important: To ensure proper cloud rendering and optimal performance in Blender:
  • Go to Properties Panel → Render Properties → Volume and enable Biased.
  • Then, go to File → External Data → Unpack Resources.

This scene has a lot of detailed and realistic models which I modeled for it, such as a nest with eggs, an oil lantern, various types of flowers, grass, ivies, mushrooms, plants, trees, a shovel, a pickaxe, and even a realistic 3D smoke for the cabin's chimney.
There are also realistic rocks and trunks in the scene which help to enhance its overall look.

I have also made two lighting setups: one is a daylight setup with a realistic sun color using blackbody with a little bit of mist, and the other is a dark and foggy setup with more fog and nice lights in the cabin and a shadow behind one of the windows.
I have also made two sets of HDR node groups in the world nodes to help them blend with both light setups.

Hope you like it! =D
