Here, you can see the atmospheric details I used in the sky - a distant group of clouds and a really soft sandstorm.
I filled up the sky with more realistic colors and applied a soft light on the horizon.
The creation of the sky and atmosphere
Step 11 The final details
It's time to leave Earth. I put some globes in the sky to indicate objects in space.
I also gave the scene some sense of life. I added parched branches among the layers of sand and a single poor bush try to survive the heat. I also added the driver's distant silhouette to the scene.
I placed some 3D concrete columns buried in the matte-painted desert field, and added the chain render and vulture's shadow to the scene, along with a soft dust effect close to the surface.
Finally the Vulture was placed above the shadow on the matte-painting (I made the vulture's layer group visible). I also modified the final scene with a soft color correction and added Chromatic Aberration and the Vignette effect, as well as a really soft additional Z-depth to the scene.
