How to implement a 3/4 perspective camera

I am trying to implement a camera that will give me a result like this.


I am unsure what my rotations and other settings need to be at to achieve this, and not distort the pixel art. Does anybody have any advice on how to tackle this?

In the Inspector, set the camera Projection field to Orthographic, Size to 10, and the Rotation field to (45,0,0) - this will produce a similar effect. Tweak the Size and Rotation to get better results.
