Lovely reflections, colours.
The fly in the ointment for me with both images is that the grass etc in the foreground intrudes into the edges of the frame instead of being either entirely IN the frame or leading cleanly out of it. At the same time if they are cloned out then then it makes a mess of composition because there's too much space at the bottom of the frame, requiring cropping into the usual pano for this type of scene. I've never been there, so don't know what other compositional options were available, but the second image with those 3 rocks on the LHS looks like it should have offered some interesting possibilities.
Your portrait version of this scene solves this problem by better encompassing the grass as an intentional compositional element, rather than an unfortunate intrusion.
