How did you make the first one? As far as I know (and correct me if I'm wrong) HDR requires blending different shots of different exposures... I hear you can 'fake it' with a RAW image though. Is that how you did it?
Looks good though! I like the second better, I really see the range in it. I prefer your first post of that image, but I usually prefer a little bit more saturation so it's a natural choice for me.
