What does it require in Unity to create a simplistic and stylized art style similar to these (Unity Real-Time Development Platform | 3D, 2D, VR & AR Engine and https://edge.alluremedia.com.au/m/k/2018/06/monument-valley-2.jpg)

What know how do I need to have? What aspects of the engine do I need to learn to recreate this? Etc.

Basically, what I’m trying to say is that I’m fairly new to Unity and I would like to be pointed in right direction from people who are more experienced and knowledgeable of the engine.
I don’t need specifics; (unless it’s comprehensible for a beginner) all I would like to know is what should I be looking into in order to achieve the art style I provided above.

Focus on two things, shaders and lighting.

A good place to start would be to do a couple tutorials on using Shader Graph (Check our Brackey’s tutorials on YouTube)

After that, have a look at the Unity Post-Processing tools. You can get some really cool effects just by playing around with the color grading.
