Test render of the self made HDRI (the entire scene is illuminated solely by this HDRI), town facing with the greenery at the viewer's back, in a 3D space:

Test render of a mirrored (the image is not the HDRI, but a refraction of the lights of the HDRI onto a large reflective spherical surface), very high zoom level, detail of the HDRI made by myself, in a 3D space:

Test render of the opposite direction of the self made HDRI, greenery facing with the town at the viewer's back, in a 3D space:
