I like the original more. Beautiful photo! I only agree with the oversaturation with the cyan in the foreground. For the record I think the silhouetted rocks add to this photo and I would not use HDR or even bother trying to get any detail in those rocks. No offense to anyone that has comments in this thread, but I think there is way too much emphasis put on detail in areas like that since technology like HDR came out. Silhouette shots are fantastic and this is a great example of how nice they can be!
