Very dramatic improvement.

Nice improvement, although I'd say it is oversaturated on the bright green - yellow part (which actually gives away it is an HDR shot). If you could lower the saturation a bit it would improve the image more IMHO (but that's my opinion, feel free to disagree )

I have reduced the green/yellow saturation as suggested

Just beautiful, nice improvement.

Great improvement, not just due to HDR but mainly because of the change of light. In the first image light was shallow, second image has much more depth.
