First time using Corona

[CoreyMBeaulieu]

This is my first time out using Corona. it took 8 hours to convert an old scene with tools on this forum and complete this render. I used PT+PT and an HDRI with a very low intensity sun for stronger reflections of light. 16 hour render time with one machine. I set it to 500 passes and just let it go, but it likely was complete much earlier as I checked on it at 8 hours and I don't see much change in the image.
