Not a bad start, but if I'm honest the story lacks life and flow - there are far too many info dumps along the way that you could work into the story more organically. There's a saying 'show, don't tell' used for writing, which means wherever possible show what it is you want to describe to the reader in action, rather than narrating about it. For example, rather then describing the throne at length when MC walks into the throne room, you can have the queen sit on it and interact with it and MC observes it that way, or maybe there are servants polishing it or such - this makes the info deliverance more dynamic.
But this is especially applicable to introducing new characters. Rather than describing every detail of their face & body, instead describe the most notable, important features - the things that immediately strike the MC when they see them. For example, if a person is half-machine, you're going to notice that far more than their hair and eyes color. You can of course mention other details when the character pushes back their curls or winks their sparkling [color] eye, or has a habit of sniffing a lot, body language, etc, but work it into the character's interaction with the world. The MC might stare at a certain feature and that could make the characters feel some sort of way, or another character could warn the MC about something notable about the character before/during meeting them. Maybe the MC meets them in an unusual way, or they say or do something strange or noteworthy that shows their personality. This serves to makes the characters more engaging from the moment you meet them and allows the reader to start deciding how they feel about a character from the first word.
Also, when you introduced the first two friendly characters, Estell and Amare, at no point do they tell the MC (or the reader) their names, yet they're narrated by their names the page after they appear. I was wondering who tf they were until I came back here and read the RO section.
Another thing that's really, really important, you need to think of this from the MC's/readers POV, not your own writer's POV. If I woke up on a strange ship about to be experimented upon, some time should be taken to show the MC's confusion, panic, fear, helplessness, etc about waking up in some foreign place. If this isn't their first time waking up on the ship (if they're in-and-out of consciousness), then you can narrate it with a bit more awareness, since it's not all new (but still frightening, etc). For a decent chunk of the start of the story MC should not be comfortable with their surroundings if it's brand new and completely alien from anything they knew. MC might stare at species they've never seen, act erratically or irrationally, etc. As it is right now, MC accepts all this new stuff as if it's just another day. Even when MC is told they're a demi-god it's like being told it's raining outside, when instead it should be one of, it not THE, most earth-shattering revelations they'll ever hear: their entire identity has just shifted, and everything they thought they knew about themselves. You need to take a little bit of time with such huge moment.
NOTE: If MC hasn't been abducted from earth, you need to work how they got to be there, or what they remember of it, into the introduction, unless they have no memory of where they came from before they were on the experimentation table.
In short, you need to step into the shoes of your characters when you write them, FULLY, including the MC. Forget what you know about the world and characters as it's writer, and just focus on what that single character knows, and how they would feel in the given situation. It will makes your writing a lot more dynamic and captivating.
I hope this helps a little! Good luck!
