Your image looks great! As for the blotchiness of some of the lighting, 
I'd suggest you take a look at a small experiment I made some time ago 
on researching the two-pass-radiosity-technique that was "developed" by 
several members of the newsgroups, my research also went a little into 
photons, using shadowless for the light-objects etc.

As for the images you linked to, I expect some of them make use of 
post-processing or even HDRI techniques, which POV-Ray doesn't natively 
support (yet, I guess, it'll sure be there someday). I often use the 
original image, raise the contrast stupendously, then put a heavy blur 
on it, and finally layer that on top of the original image using 
additive-composition. This softens the image considerably, but depending 
on how much you blur, how much you add it and how much color you retain 
(all subject to tweaking), you get effects close to glaring highlights 
or colored saturation, which IMHO often improve the image, if not overdone.

Tim
