I think you have a great story idea!! It's interesting, vivid, and has just the right amount of fantasy and real life. I definitely want to read more!
Your story seems to have some gaps/missing parts. I feel sort of lost because there are many big events going on (Like, all of a sudden after the main character seems to like Mama Tera's son, he saves her from the awful dudes.)The story progresses too quickly for me to catch up.
You could expand on some scenes, for instance, um, when she sees the writings on her sister's arm and later finds out about her soulmate. You can definitely put her sister getting together with Max a little later.
You're probably in the writing stage where you're still figuring out the whole story plot and where to place scenes.
I agree with @Marionette87 about getting to know your main character. Work on understanding her first. You can look up character questionnaires (The Proust questionnaire is a great one, also the Gotham one too!) and try to get to know who Allania is.
All in all, I really liked it and I want to read more!! Great job!
