HDR on a foggy morning!

[riz_sat]

Hello everyone!
Well a few days ago I woke up and saw foggy morning so I grabbed my equipment and went to a park nearby. So I took some photos to make an HDR from.
By the time I reached there the fog had started to get thinner slowly,
I used Nikon D3000 camera to take these HDRs, camera was fixed on a tripod and I took a number of exposures at different stops.
First HDR,

The photo above is cropped.

My question here is how do I correct the right side of the photo as it looks quite unnatural to me as compared to whole photo?

Second HDR,
By that time the fog had almost disappeared,

Thank you for looking!
and I would really appreciate C & C

Lose the watermark?

I think the saturation is to much especially in the greens. They might be good for black and white
