Please take my critiques with a grain of salt, I am not an expert on character making and I'm not claiming to be. These are just some suggestions you can use if you'd like, now I hope you enjoy the review ♡

ame/nickname - 10/10

Nice but common!
(Commonly known names to me is a rather good thing, because you can give your character's first name out and have it burried under god knows how many people)

Age - 9/10

Birthplace - 7/10
Ngl, I really like how a killer is from the place where almost all local
animal life could take you out if you're not careful
But Australia jokes aside, I like the birth place but I would be specific about where in Australia she was born in, I see you did this for where she moved to, but to me it's inconsistent
Like my Liz

My lovely Elizabeth and her gorgeous brother Daniel, I've had them since 2015
Liz was born in Anaheim, California then moved to Quebec, Canada along with her mother and younger brother, if you'd like to read why she moved to Quebec, you're more then welcome to read up on her!

But I'm getting off topic

I'm not gonna comment on the species, race, height, gender or birthday as it seems unnecessary!!

Weight - 9/10

Nice weight, it should get her around much quicker but it should also be somewhat of weakness if you haven't done that already owo

Occupation - 6/10
Bit predictable imo!

Weapons - 5/10
Good for the daggers,though I would like you to be more specific, are they trench knives, Bc-41, parrying daggers or stilettos?

The gun feels really unnecessary ngl
Depending on the gun, it can work but you have to work at it
Also, I feel I'm repeating myself when I say please be specific of what type of gun she's using uwu

The base look - 7/10
Plain and unmemorable, though still rather cute

The tat - 4/10
Eh, not a fan of tattooed feathers, though the tattoo is fine it's just it's placement
If it's not covered during a spree that can be an identifying mark, so I'd cover up it up or place it somewhere else

The hair - 2/10
Not a fan of the blue tips especially when you have that face claim. That would also be another identifying feature, and, ngl, the blue is gonna make her stick out like a sore thumb
Though, admittedly the other cps have that issue, and that's one of the problems with Creepypasta for me
Plus, as a certain someone said when I brought it up to them owo

The oufit - 3/10
First the jacket, the collar of the jacket would stick out, so I'd switch to something a bit plainer, something not so, out there
The earrings, I'd either change the earrings to studs instead of the small dangly earrings, because the small dangly earrings can get caught or slip out
The boots, heels are not practical in the field, weather the heel is thick or thin. I highly recommend changing them to some kind of flats
We don't want her to break that heel and break her neck

I feel like I'll be repeating myself alot when it comes to the overly vibrant blue. But at least you changed the boots to something flatter.

Personality - 5/10
You'd think if she had more of a heart she'd be somewhat hesitant on the field then ruthless and cold.
It feels out of place imo

Nothing of note here

Ok, here's where I lost some interest in the character.
T

he middle one is perfect
But it's the other two that throw me off, I'll explain further when we get to the 'other' section.

Now I originally wasn't gonna comment on this but a friend pointed out that the creator didn't state how her mental illnesses make her react to things except for the depression

Oh man, get ready
Ok first, is she like a superhuman? If so, why isn't it stated in the start of the bio? Is she a normal human who jus gained these powers? If so, please elaborate on how.
Not a huge fan of the powers I'd either change her species to something more magical, for lack of a better word, give her a companion that she only can see with those powers, or just get rid of the powers.

Now I'm gonna save the backstory for the next part. But I hope you don't take my criticism to heart, these are just my opinion!
