I have two comments. First of all, I see in your non-blurred render that the
POVRay you have doesn't have Lars Hassing's Torus Patch. Take a look at this
page, where Lars describes the problem, and provides the fix:
http://www.hassings.dk/l3/povtorus/povtorus.html
(Note that the fix is included in POVRay 3.6, but he provides a fixed engine
executable that you can drop into your 3.5 install.)
Secondly, I agree with you about the focal blur not looking very good. This can
apparently be corrected by tweaking the blur_samples, variance, and confidence
settings. Take a look at the last two paragraphs of the Focal Blur section of
the POV-Ray documentation here:
http://www.povray.org/documentation/view/3.6.1/248/
Of course, in general, the better you make it look, the longer it will take to
trace. They do provide a suggestion for "high-quality" output that isn't
"unacceptable slow", but it's hard to know what they mean without trying it out.
