Thanks for the kind words Ro-nin.
If you need help/advice then just ask.
If you have the full version I'd say start with rendering at 0.8 quality, AA 7 and GI 2/2 with a resolution of 800x600 or 960x720. Depends a bit how fast your machine is.
I like the mitchell-netravalli filter most times, but maybe in this case with non-insane rendersettings the cubic b-spline will be a good option as well.
