Number 2.

#1 has a good WB and natural look. #2 is way too blue for my taste. You could probably get what your were going for by using a brush to change WB on the sky/clouds only, while keeping a more natural look to the pond/plants. My opinion....worth what you paid for it.
I agree with Brian and Grahame. #2 looks very unnatural.
I like the 1st image, the highlights just need controlling if possible.
The last one looks good Steve
