Now, I'm definitely not as versed with novels as I am comics, but I'm not opposed to reviewing some good ole' literature every now and then. Since your story pretty much hasn't even begun yet, I'll mostly focus on your techniques.
Starting with repetition can work, but only if it's really done well (in my opinion). The first two sentences, while poetic sounding, don't make much sense in regards to what follows. Even if they are alluding to something that either has occurred, or will occur, or otherwise, cutting from these seemingly unrelated imagery to the protagonist in a different setting without warning was a bit jarring and confusing. If you really want to implement this, have those first two sentences lead into at least some sort of explanation or context. I like to think that the first thing the audience reads should be gripping, eye-catching - which what you have written certainly is - but it should also make sense.
As for the rest of this scene, it has a nice flow, with characters 'characterized' by their actions as well as words, which is very good. There's certainly a level of mystery and intrigue surrounding Indigo, mainly how he turns his freaking secret home invisible!
As for your newest scene, it didn't really do much for me, but understandably it is more of an exposition kind of thing. We do learn a bit about the world these characters live in, but only a little. Indigo obviously is being paired with some stranger against his will, it's a trope we've seen before...... at least, I'd say that had I not retroactively read the description of your novel. Knowing that Indigo was born a girl and thus is expected to fulfill a certain role in his society pertaining to that is certainly a very cool topic to play with, and I'm excited to see where you take this.
That being said, the fact that I got this from the description and not the novel itself isn't very good. I understand you literally have only two pages out, so you'll get to that eventually, but my thought process of "this is just another one of those stories" might be what other people see, and they may never read the description. Just something to keep in mind.
Something I think you should work on is really taking the readers into the protagonist's head. What is he thinking, what is he seeing, what does he think about what he sees? I want to know more about this person and his ideologies!
Bonus Round: Let's get some more imagery! Sights, smells, tastes! Water trickling over rocks, its sound carried by a breeze. Birds frantically chattering, hopping from branch to branch in the trees above. Immerse the reader in their environment so they won't want to stop reading.
