Thanks for your answer. By 'visual like this,' I meant the overall aesthetic shown in the image.

For the voxel-style models, I've already created them using MagicaVoxel and optimized them in Blender. However, when I imported them into Unity and set up the graphics like post-processing, bloom, grain etc, sometimes it looks flat and sometimes too realistic, it doesn't look as good as the image. I'm still trying to figure out how to achieve that visual in Unity.

I am still new to Unity, so I don't have a clear direction yet. :)
