How to Make a Warrior Cat OC

Review my OC!

I wanted to do something a little different!
The idea is what it would sound like, you criticize one of my main OCs!
I'll post the bio below:

Name: Driftshade
Gender: Female
Clan: WindClan
Rank: Warrior (at death), was deputy but resigned
Age: 37 moons at death
Appearance: Reddish-grey mackerel tabby with yellow-orange eyes, two parallel scars on her left cheek, missing left ear
Personality: Very reactive, is very calculating during battle, inventive and able to read people, often says things she doesn't mean to and has a lying problem
M/C/K: None, and isn't interested :3
Mother: Palefire (dies of an infection when Drift is a young warrior)
Father: Hawkflight (dies of greencough after Drift dies)
Brother: Redfrost (she kills him (exPLAINED))
Sister: Dawnstream (is killed in a raid against RiverClan)
Cause of death: Drowning
Backstory: Driftkit, Redkit, and Dawnkit were born at the start of Leaffall and shared the nursery with kits Vixenkit and Aspenkit. The three often played a game where Driftkit was the the deputy, Redkit was leader and Dawnkit was the medicine cat. This became their plan for when they were older. However when Aspenkit and his sister got apprenticed Aspenpaw became the medicine cat's apprentice. Driftkit said that by the time they were apprenticed Aspenpaw would step down (this started the lying).
When the became apprenticed Dawnpaw had recovered and was happy being a warrior. They trained hard with their mentors and even though Driftpaw's mentor Rainpool was a little too daring and sometimes got them into trouble she learnt a lot. When they were almost warriors Redpaw got a prophecy: "When the blood runs red, the rift between the wind and the river would be no more."
The clan as a whole thought this meant Redpaw would stop an oncoming war between WindClan and RiverClan, and when they became warriors (Driftshade, Redfrost and Dawnstream) his clanmates pressured him to attack, and he did, which eventually started a war, the one in the prophecy. Driftshade personally hated this, and tried to convince Redfrost that this was wrong but he had been corrupted by the peer pressure on him. She got an apprentice, Ryepaw, who she tried to train to be peaceful amidst the war.
One night, after Ryepaw became a warrior, the clan made a final plan to take out RiverClan. Redfrost was to lead a raid with his siblings, and a miscommunication during the attack led to the deputy and Dawnstream's death.
Driftshade got extremely angry and blamed Redfrost for it, and their words led to a fight between them. Redfrost was stronger and faster, but Driftshade knew him better and gained the upper hand. In anger she killed him, fulfilling the prophecy, which actually meant that when Redfrost died the war would end.
Driftshade ran back to camp, and the clan saw her as a hero for stopping the war.
She was made deputy, but the guilt of getting what she wanted while her siblings were dead ate at her until she resigned. She started hallucinating, mostly reliving the events of what had happened.
One night, it got really bad, and thought her brother and sister were chasing her, causing her to accidentally fling herself into the gorge.

Good luck!
