How to get this look with freestyle

Hi all! I am currently trying to make an animated short. I am still in the concept stage. While I was surfing through the web for art inspiration, I came across some Zootopia Concept art. Can someone tell me how to get the same look for a final render? I really would love it! Thanks a lot!

Please tell me in detail because I want to recreate it. Please also see if Eevee can do it, because real time rendering would save me lots of time and resources. Thanks again!

I’ve never done it myself, but I googled up non photorealistic rendering, and watercolor blender, and found this.

Might make for a good place to start.

Thanks will look into it!

Anyone else any other ideas?
