Name: Ivypelt
I like the name its very simple yet elegant
Age: 26 (89 at death)
Seems good
Appearance: a long limbed grey and white with tabby markings and soft green eyes
I like it, when I first read it I randomly thought of the "It's so fluffy I'm gonna die," scene in Dispicable Me
Gender: She-cat
good
Personality: a shy skittish she cat who prefers to be alone and is often quiet and rarely speaks
Good, though often quiet and rarely speaks is basically the same thing when put to together, I have no suggestion on how to change it, so you can leave it
Strength: Hunting
Good
Weakness:Patrolling
Good
flaws: she has two missing teeth when she hit a rock while hunting
That's a unique flaw
Clan: WindClan
Yes! WindClan is pretty under rated for a main clan, its always good to see a windclan cat
Rank: Warrior
Good
Backstory: Ivypelt was always a quiet kit from the day she was born. She was an only kit. She rarely snuck out and often sat alone in the nursery and never really played with other kits. She was made apprentice at normal age and her mentor was a more talkative cat named Loudfur. While training to hunt during Leafbare she hit her jaw on a rock and lost two teeth on her bottom jaw. Other than that she lived a normal life and died of old age as an elder.
I like this too. Is she a lonely character? And the name Loudfur is on point
Death: Old age
Cool, not all cats have to die a big death.
Overall, I like your character, she's unique but easy to remember
