That looks really good! Very nice aesthetics with the sun behind the temple!
Love the cactuses and the desert - beautiful!
If you’d like those long, sunset shadows, select your lamp, and go to the Object Data Properties tab on the right. It has a green lightbulb on the tab. Change the light from Point to Sun. (You’ll need to adjust the strength. It uses a different system than Point, and chances are it’ll be too strong when you switch).
Sun lights work differently, too. A Point Light sends rays out in all directions from the point. The Sun Light doesn’t. It really just provides a direction. As you rotate the sun around, you tell Blender the direction you want the sunlight from. All light rays will run parallel, and you’ll get the long parallel shadows.
