spheres should turn to ellipses, afaik
A sphere is a perfect circle from any angle.
That's why the sun never turns flat.
Its probably its the only shape that never changes.
Antenna not necessarily broken perspective it might not be shaped like a TV aerial.
Obvious broken perspective are the tops of the bottles, the rings around the pipes (just the vertical ones).
They should be elliptical.
Without seeing engine lighting its hard to comment on light source but it would have to be pretty complex to handle all these shapes properly.
IMO it would be better to have the light from overhead and towards so it slightly lighting the front of objects and allows for highlighting on the edges of vertical and horizontal planes.
Some offset to one side also makes better shading opportunities to describe forms.
