Dyson Ring in Venus Orbit

Put at a orbital distance (semi-major axis) roughly similar to that of Venus and given a slight inclination as to minimize blocking sunlight to Earth. I suspect you wouldn't be able to see the side facing Earth (away from the Sun), especially with this lighting, but that I was added, however faintly, for structural context.
