A matting question...

[ROL]

And, as far as the dyptich term is concerned, I have always taught that a dyptic is comprised of two images that are designed to be shown together but don't necessarily have shared elements. These images are indeed a two-panel panorama. I wouldn't consider them a diptych.

Honestly, I wouldn't comment on the images themselves except to say that it is not easy for me tell what the reason for presenting them together might be, that being your decision as "artist". Examining them once again, they do not appear to me, as a casual viewer, to be parts of a panoramic either. I just don't personally get the relationship they have to each other – but that relationship, if it exists, shared elements or not, would make them a photographic diptych.

...But...I do have to admit, I want to place the rock on the left even though I know it's not supposed to be that way.

Print them backwards and switch right image with left image...

Us carbon printers do it all the time...

I thing the relationship between the images would be much stronger without the black borders. I think leaving the black borders would be much more effective if both of the images much darker overall, but since they are not and you are showing them together the black border tends to cause an unnecessary separation.

i like more matte width
to me it looks like it would feel a bit closed especially being so airy

and more middle space
