Name: Briardrop

Hmmm.... I don't think I've ever heard "drop" as a suffix. Nice.

Gender: female

You mean she-cat? :3

Clan: Juniperclan

Interesting Clan name...

Rank: medicine cat

Chill

Age: 31 moons (dies at 52 because of her injury)

All seems well

Looks: Brairdrop is a beautiful she-cat with black, white, and brown colors of a torbi. Her fur is not too long but not very short. Her toes her white and her muzzle is also white with hints of brown. Her torbi colors are splotched on her pelt and mixed. Her underbelly is also white. Her eyes are a deep shade of ivy green with lighter rings around them. Her leg has a black scar covering it from a fire

Do you mean "tortie"? I really like the description, she does seem like a beautiful cat! 

Personality: Briardrop is very kind and sweet, though she can be very snippy and sarcastic. She is very gullible and is pretty clumsy, despite being a medicine cat.

This personality is balanced, but cliche and a little bland. Try adding a few more traits.

Backstory: when Briardrop was a kit she always dreamed of being a medicine cat but when her apprentice ceremony came around her fighting and hunting skills led to her being forced into her becoming a warrior wait, hunting and fighting forced her to become a warrior? Don't all apprentices hunt and fight? Maybe you mean that she was really good, but I still think that her leader would have let her become a medicine cat apprentice no matter what... But almost five moons after she became a warrior she found a mate, Runningpelt, and they had one kit together,swirledkit Cute name! Also, I'm glad she had the kit before she became a medicine cat, not after. Shortly after they had their kit a fire rattled their clan and she burned her leg very bad. Her dream of being a medicine cat would come true, or so she thought, because of her injury. But during the fire, the medicine cat died. And there was no medicine cat apprentice so she took on the role of a medicine cat, having to give up her kit. Wait, so did she have a hard time struggling to learn the herbs? Did the former medicine cat visit Briardrop in her dreams and teach her? Did Briardrop just know what herbs to use? SO MANY QUESTIONS
M/K/C: runningpelt, swirledkit

In total, I give this oc.... 7/10. The background needs a little work, and her personality could be added to. Overall, though, it's a pretty nice oc!
