Plot to cliche?How?How can I make it less cliche?

To be brutally honest, I feel like this is a mix between Ella Enchanted and a Taylor Swift song. I do like how the main character dies. I haven't read a book where that happens in a while. I would suggest something more simple than the kingdom having ugly people and that's why Lilliana comes to work at the castle. Being just a regular servant, with beauty, is fine. Plus, it might add a more realistic view of Icarius and Lilliana falling in love. I'm not sure if Katia just wants to be queen and that's why she tries to kill Thea. Maybe Katia wanting to claim the kingdom as her own would make more sense. Even though killing Lilliana is a good twist, maybe her becoming a spirit could add even more to the story. Thea could stay evil and marry Icarius, but Lilliana could come back to Icarius in spirit form in secret and he search for some type of thing to turn her back to life. I mean it is a fantasy novel, isn't it? Unless you add more twists, the story will probably be passed by because it would be too much of the same thing that people have seen before. I really hope I helped!
