The line demarcation just below center, is a little visually confusing for me.
Don't mean to start off with my usual ... ahem ... infamous 'caveats', but I am perplexed.
As a suggestion, I would have preferred the water texure to be more pronounced and I think that would clear up what my eyes see ... and yet cannont be fully processed by me brain.
Quite the undertaking here ... a very full and expansive setting. Must have been a lonnnng render. Adding in the light play and fog and and ... yeah.
Apt title ... and even without that as an interpretative leaping off point ... your work here readily conveys that which is not seen, but heard with the eyes.
This is so beautiful! When I was looking through your gallery, I just knew I had to comment on this. Colours are great and everything just works, nice job!!
