Feels like flying above canyon landscapes. Won't be easy to find lyrics for. So I'd suggest to leave it pure instrumental, optionally to insert a couple of non-lyrical voices. Another idea would be to give it a psychodelic touch by overlaying a distorted singing guitar.
I think I'll split it into 4-bar-clips just for fun and recombine them to obtain at least a 4-minute-track which can be accumulated then by voices and guitar.
Let's see... project name 'Canyoning', what do you think?

Haha, yes, this is weird. Yesterday I extracted 3 clips from Necromanos' theme and uploaded them to Splice (I hope you don't mind, Necro, but I really was flooded by eagerness). While playing with them in the sequencer, I had these canyon pictures in mind and also had strong impressions of a man climbing through the rocks and caves at the canyon's ground. This man, deeply touched by the natural rock formations, is dreaming of being weightless and flying away, just drifting over the deep valley.
Then I found a couple of vocal clips which I think would match nicely. You can listen to all samples on Splice - just have a look at my recent sounds: names are starting with 'Cny' - abbreviation for Canyoning.

A "windy" sound is an excellent idea. In fact I already seeked such a natural effect and found some candidates. Maybe an analog synth noise will work as well. It should be loopable and have a length of about 4 to 6 bars (at 106 bpm).
