First of all, King's right, you should look at other approved characters to get a feel of what people are looking for.
A few things. First, no 'soon to be' just, student, and list what year she's in too. For appearance, you're lacking a bit, such as height, weight, figure, and maybe a few special facial things. Eyebrows, jaw, cheekbones, nose, skin tone, lips, something to give us an idea of what she looks like. And you have a lot of sentence fragments. Usually it'd be fine, style thing y'know? But they're not really necessary here, so you may want to change that.
History. Lot more needed here. Just because she doesn't remember does mean that you can leave it out. You still have to write it out. A few suggestions would be the names of her parents, what they did, where she grew up, how she felt about her parents, how she was treated, how she did in school if she had any friends, and what led to her being orphaned then losing her memory. After needs more detail too. What was the huntress's name? Where'd she find her? An orphanage? In the streets? Why'd she adopt her? Was she on the older side or the younger side? How else did she treat her? How did she do financially? Also, just a note: Amnesia, though it may sound easy, is honestly overused and harder to write than you think. The huntress taking her in is also a little overused. There's not big problem, but I'm just putting that out.
Her personality needs more as well. Likes and dislikes? Sense of humor? Is she smart? Does she warm up to people easily? How does she treat them when she's warmed up to her?
Combat behavior definitely needs more work. Adaptable, sure. Adapting to ANY change? Eh... Is she quick? Slow? Hard-hitter? Deals little damage at a time? Gets things over with or draws it out? Stamina? Does she kick a lot? Stabber? Slicer? Blocks or dodges? Weaknesses are very much needed, as it balances them out.
Finally, don't just say: My profile picture, just put the image in the profile. Specifically, put it in the Appearance section, in a spoiler. Like this:
