Jesus H... holy halos.
Way over processed... that's not HDR, I don't know what that is - there's no detail in, well, anything.
Looks like a negative image. What did you do that image?
+1 over processed. but for some reason i like it.
Converted into HDR? How many exposures were used?
try the luminosity slider to help back off the halos
be sure you using the ghosting function as well as the clouds are giving you a problem .
are you using the latest vesion of photomatrix as should help
