The original is certainly beautiful but I do love how you brought out the shadows in this. I love the stronger difference in tones now. The clouds are wonderful!
I strongly prefer the Topaz version; the original is quite strong, but seems soft at distance. For me, the darker clouds confirm the diagonal visual flow through the frame. Very nice shot!
I think the original is quite beautiful to begin with. To me, this version is a little too much. I like what you did, but I would back it off some. This seems to have too much contrast (too dark), and the sky seems overbearing instead of uplifting, as it is in the original. Also I don't get the same feel of distance in this version. It seems to have flattened the scene. I like what it did to the texture of the tree and marsh grass, but I think the grass is a bit overdone too.
Robert, this is beatuiful. This is what I envision using Topaz for, not too much, just enough to bring details back and add some punch to colors that ordinarily would not be seen. Great job.
