Just quick testing anime look, no complex shaders I used, just Principled BSDF and some minor tweaks. I have been tried using 3 cell layers by Blender's toon shader demo, but it doesn't work best for this scene. (maybe because I don't know how to use it). Rendered with EEVEE / 64 Samples
*for the background images, I found on Google, and import it with Image as Plane, and for the Material Node, I just use Emission shader to it.*
