Great HDR treatment, and a fantastic looking sky. Love it! I don't think there is that much of a halo, and I would tend to agree with you about taking a picture with a near white sky. If you didn't use hdr the shot would have looked bland and very ordinary. Which programme did you use for the hdr? The only very minor criticism I would have is that the main tank could do with straightening a degree or two.

I am glad you get something out of this photograph. Subject wise it is not the most interesting and although the treatment works to an extent with this subject the halo and the colour shift at the top just push this image too far and I cannot get anything out of it at all.
Sorry but just my opinion. :shrug:
