In Clip Studio Paint, you can, as I have here, construct 3D objects from ‘primitives’ such as cubes, spheres and polygonal shapes or you can import ready-made objects such as the figure and the cart. I’ve followed these closely as reference, drawing in my normal pen and tone method on the iPad.
The advantage of constructing a setting like this is that I could then have the figure walk around to the other side of the scene for the next frame in a comic, or even show a bird’s-eye view.
