Looks really good.  I'd love to see the source, especially that felt 
texture.

  Even a red billiard ball will have a whitish reflection/highlight from
a bright source of light. (This is due to the physical reflective
properties of materials.)

  It might look better if you allow the reflection to have the color of
the incoming light.

  Forgot to mention that this will make the black ball to have a
reflection as well, which will make it look better.

where should the light(s) be placed? i'm guessing somewhere by the "window", but
the background is just an image.

I suggest cranking up the ambient on the ceiling lights to something
ridiculous--like 5.0 or so (unless it's an HDR light probe, in which case i
don't know what i'm talking about, so never mind).  I want to see some
HIGHLIGHTS.  :-)  And since billiard balls are non-metallic, they should
reflect the colors of the lights and objects that they're relecting.  I
generally use something like this for glossy things:

   finish
   {  reflection { 0 0.4 /* no color here */ fresnel }
      specular 1 roughness 0.001
   }
   interior { ior 1.5 }

Well, it is HDRI, so any help in that regard is appreciated.

The billiard balls are all CSG constructs. The only image mapped textures are
the HDRI and the felt for the table.

  I didn't suggest adding light sources. I suggested defining a regular
reflection for your balls which do not filter the reflected light.

Very nice :))

One bill 15, the lower white part have some gray spots not visible
elsewhere, is it correct? Or strange normal, or glitches from radiosity?

That is the reflection of the felt. Ball 10 shows the same.

Excellent work, btw, jhu!
