Welcome, Quinn!
I like the way you've framed your character up--in the respect that I think she works well as a Ravenclaw. She fits very well there, and I think, as she is, she would be a solid candidate for that house.
However, the issue I struggle with is that on the canon list, she's a Gryffindor. Right now, there is no logical reason the sorting hat would ever have made her a Gryffindor.
I'd like you to revisit it and find some reason, even if its an underlying reason that Quinn doesn't show very often, that makes her a candidate to be a Gryffindor. In order for her to be a Gryffindor, there are a few characteristics that she would need to have at least some elements of. Gryffindors are, first and foremost, loyal to those they love. Their loyalty supercedes all else. They'd toss themselves under a speeding bus if it would save someone they loved, and they wouldn't think twice about it.
They're fighters and they are interested in the greater good for all people. They are not supporters of the dark arts because that would imply, generally, greed and self centeredness, and that would be counter to a Gryffindor's nature.
Can you revisit her app, please, and see if you cant' find some way to make her fit the canon requirement for her?
If you need help, let us know!
