Look, I've read Twilight back in the days, and even then I wasn't the intended audience. But it was immensely readable, and though cringe at times, it somehow hold together.

This does not. It's a bucket of cringe wrapped in many useless scene to fill up pages. And then you have so many cheap betrayal and "twist", you can only roll your eyes at the author. YA doesn't mean the reader is stupid, Cassandra.

The multiple references were exhausting. It didn't help me like or admire the characters, nor the author for that matter. It was just a weird flex and rarely did it support signficantly anything in the story. It just broke what little flow it had going for it.

Finally, Clary and Jace are stupid names. You can still do self-insert with a name that doesn't copy yours that much, and a name that isn't so grating. But I guess it's fitting since both characters are horribly annoying, even when they're not supposed to be.
