3D top-down with 3D sprite-stacked objects (z-elevation tricks)

Hey guys,

For a new game-idea I try to use Construct-3 to create fake 3D like top-down game with 3D objects. My game wont have much objects on screen at the same time, so I can afford to create lots of stacked sprites.

I am using sprite-stacking plus the z-elevation to create the desired effect.

My question is: is this the right way to do it ?

What are the alternatives ? Is there an easier way ?

The example has a building, a buildin with a balcony, a pine-tree (solid 3d object) and a red-framewire-ball (complex 3d object). The buildings are immovable. The red en green objects have ball-physics.
