Here is a review for et-tu-brutus

My comments will be in bold

Basics and grounding

Coolio I love professor characters for this universe.

Character information

This is pretty good for the most part, but I have an issue with the age. She seems incredibly young to be a professor, since you often need to have studied subjects at a higher level and you need a university degree to be able to teach. Obviously it's Harry Potter so Idk if this applies but it is set in the UK so I imagine there would be sommet goin on there you feel me, so maybe just age her up a bit.
Maybe add more detail to her personality and develop that aspect more too. Her appearance is well described and detailed, so maybe try to match that same energy with her personality.

Relationships

These are all pretty good and well thought out. Just make sure they help the character grow.

Backstory

This is pretty good but maybe add some more key events or significant moments in her childhood and school years so that she feels more fleshed out and developed.

Other

All checks out this works.

Stats

Stats are balanced no issues here.

Final thoughts
I think this character fits the universe well and is pretty well thought out but just work on a couple of things and develop her further to go the extra step and make her even better.
