Definitely a good prospect for young adult/teen vampire fiction. Alice is a relatable character, and you do a fine job clueing the reader into her emotions, and the reader can feel the changes in personality and power with her character as the story progresses. So you certainly have a solid foundation for a fantastic story.

This all said, you really could stand to benefit from a full edit, especially when it comes to grammar. For example, you repeat at the beginning of Chapter 5 that Alice is a vampire, when it was already established in the previous chapter. I suggest https://prowritingaid.com. You can establish a free account there, and it should help you along. The one thing that was kind of a "turn off" for me was the chapter lengths. You tend to utilize too many "parts" in each chapter, and it takes away from the readability. Try to break up the chapters and condense them a little more for clarity, conciseness, and a much smoother reading experience. I would also suggest making a decision about settling on third or first person, because that also could take away from reader interest and confuse them.
Overall, though, a very good prospect, which with time and effort, could be turned into a publishable story. Keep at it and you'll do great!
