Now I am confused. (click for full size) Indeed view angle pays a mojor role. For this test render, the view was slightly changed just to get the roof in the picture, and? ? 

The floor improved by 500% ? ? ? ? ? (was still black in the preview)

Lessons learned and observations.

1. The roof did indeed render all relections, even put a shadow for Aly's body around her feet.

2. When watching the render go, I noticed the red and yellow imperfections in the reflection.
   Where do thy come from? Initially I thought from the floor, But?

3. The middle ball, and the side walls render perfect.

4. The floor: vast improvement on the floor. Just by slightly changing the view angle.

5. Major imperfections? The red and yellow on the roof,  the bue ball, the white between Aly's legs, the line on her chest, and the arms of the main figure. The reflected arms on the side walls are perfect..

Way past bedtime now.
