Nice postprocess, Christophe. I liked both of the photos. Each one has its own beauties. The original one has very natural look and this one has impressive look.
I think Bob's onto it, the hdr process has made more of the blue light of shadows, maybe a touch "too" much. :) But it has also picked up details and clarity over the original shot. Worth sharing the difference Christophe.
Well snapped pal.
