Heya Skylar and welcome to HPRPG~!
However, before we can sort you, there are a few things that need editing. First, you capitalize a lot of things that don't require it. ^^ You don't have to capitalize the first word after commas, because it's not the beginning of the sentence, nor do you have to capitalize words that aren't proper nouns, names, or titles. (For example: Her mother and father fought very much and they split up with Skylar was three.) Maybe run it through Word or spell-check to catch them if reading over it doesn't? <3
As for her history, we don't really get too much of Skylar's childhood, and what we do get is just mentioned and then dismissed. We're not exactly looking for information on her family (or lack of, since you specified that she has no siblings), we're just looking for the important details and how she grew up. Was she homeschooled, did she attend school prior to Hogwarts, what did she do for fun, maybe a bit more on her relationship with Rain. Her father and her going shopping, as well as the note that she loves Quidditch, feel a bit thrown in (and her love of Quidditch can go into strengths).
We ask that you don't like the traits that make up her strengths and weaknesses. Could you give us some 'why', add some meat to the skeleton list? Why is she good at Potions and Defense Against the Dark Arts, why is she amazing at fighting and comebacks? Why is she bad at Herbology, etc? Additionally, you need at least three personality weaknesses.
And lastly, unfortunately, having a temper, being a pureblood, fighting, and the classes she's good at don't necessarily qualify her for Slytherin. In fact, they're not really anything that would qualify her for any house. What are the specific traits of Slytherin house that Skylar has? Slytherin's house-specific traits are: cunning, ambition, and power, but they are also resourceful, traditionalists, and somewhat vain.
Once you've made the above adjustments just change the title from 'pending' to 'edited' and we'll continue with your sorting from there.
