Since you just asked for general impression, I'll try to focus on that or on my general thoughts and not go into the technical writing details (I think other people have already done that on the document, which should help if you want it):
I'm not particularly hooked, BUT I will admit that I generally don't read fantasy/fiction that starts off this brutal (I read the slow build-up stories), so it's just a difference for me and you should take it into account that I'd probably not be your target demographic.
Now, I know you said you didn't want any proofreading/grammatical impressions, but to me, how the sentences flow is important. Overall, I think you've got some good sentences, some that really pop and stand out, and you also have some that feel like they could be cut. I'm sure you'll get to all that in the editing stage. Right now, it wasn't enough to take me out of the story, but I'm saying this, too, just to bring it to your attention.
But I am intrigued as to the choice to flip between first and third person. I think that it's an unusual tactic and could be a very interesting read because of it. I'd be very interested to see how the writing melds with the story in this case, probably more so than in other stories. It's definitely intriguing. It's a bit weird at this point (considering you had two third-person POVs and then one 1st-person) but could be done really well at the end (preferably, I'd like to see it come together at the end with a more meaningful reason than "I just felt like writing first-person here now").
After the section with the father, I was more intrigued. Not exactly sure why. As I said, I just generally don't read dark fantasy, or any type of literature that starts off immediately grim (which is ironic because I will admit to writing grim in my beginnings). There was a lot of telling in the beginning of this section, but it was something I didn't mind, and I think you made it work.
There are some awkward phrasings, but again, I'm sure you'll get to that in editing. I thought it very cool to have this protag that was famous, but I'm still not exaclty sure how she got there. Because it seems like a small, one-time moment of fame, but considering how big its gotten, it feels like its lasted a few years already. While I could make the safe conclusion that she has continued her art and she's just well-renowned now, I'm not given confirmation on that. But also, it's very interesting and I really liked that. I'd be more interested to see what type of art she makes and how it gains her this attention, why she hasn't been able to keep any friends, if she makes money, how people view her, and her internal struggle. I loved the throwing parties explanation and how she thinks about others and has her secret desires (Of course, my type of story would focus on this section and not the rape, haha!)
General questions to ask:
What she says afterwards is intriguing. Because I'm not exactly sure what she's talking about. So that is good mystery.
Some of the dialogue felt unnatural, though.
Now... I suppose onto the next part.
I will preface that I have never gone through this situation (any type of rape situation), so some of my questions may just be from naivety, but I thought I'd ask just to point out my general thoughts.
Now, yeah, the next section, it was okay. Not my cup of preferred tea while reading, but I guess it was fine. Kids can definitely be cruel, but it was a bit hard for me to think this cruel (though I'm not THAT naive that it wouldn't happen - there are rough kids out there). It's just something I prefer not to think about. Same with the violence/name-calling against someone that's gay. A bit much for me, and I prefer to have sexual relations of any sort portrayed in a positive light but I understand that to do that could also be a disservice, as these things do/have happened. So I didn't have a question on that - just, yeah, it was a dark scene, I guess. I also thought it interesting you chose this section for first-person, which gives me some thoughts, and could be interesting to see how that unfolds.
Overall, it's probably fine for your reader-base, story-wise. I can't exactly tell where the story is going (I don't feel I really need to know right now though - that's what the whole story is for! :) ).
It has a strong opening (what I mean by that is that some sort of "big event" happens) and seems to be one of those stories that has a lot of "big" events that happen in them. I think people that like those stories will probably like it. Whereas those that prefer slower, less bombastic stories may feel overwhelmed.
Pacing seemed fine.
