Okay, I had to take this down for a sec, because my phone is acting up, but I think it's fine now

Name: Maplebelly
'Belly' is a petty underused suffix though 'Maple' is pretty common. Unlike most people, I don't usually care how common the name is, more on how it sounds. 4/5

Past Names: Maplekit, Maplepaw
Makes sense 5/5

Name Reason: Long Ginger fur
This would be fine, except there's no reason for the 'belly' part. I'm not sure if this intentional or what. 4/5

Appearance: A long furred ginger she-cat with bright green eyes, a black nose, and a tiny scar across her flank.
I like that she has a black nose, it makes her stand out more. The long fur also sets her apart from all the other 'Ginger she-cats with green eyes' Still could use more description though, especially on the body. 8/10

Gender: She-cat
The usual 'No comment'

Age: 20 Moons
Young, but she still an apprentice so thats fine. 5/5

Personality: Short-tempered, bossy, shy, submissive, independent
I think being bossy and submissive doesn't really make sense together. Neither does they shy part. I like that she's independent though. Try adding more positive traits that go with the negative or more negative traits that go with the positive.
If that was intentional though, you should put a reason why she can be bossy and shy. 7/10

Sexuality: Straight
No score

Clan: RiverClan
That's a canon clan, so full points 10/10

Rank: Medicine Cat Apprentice
Reminds me of Leafpool 5/5

Mother: Swiftfern- Pale ginger she-cat with with Amber eyes and a scar across her snout
Good, Good. So far her genetics are making sense. The scar was a good detail, but the body type should be included too.

Father: Spiderstar- Long furred pitch black Tom with bright green eyes, and a short tail
Same critique as above

Sister: Tumbleberry- Ginger and white tabby she-cat with Amber eyes
The name is so cute! I like her appearance too, it somehow matches the name. But once again, more detail please.

Family Score: 8/10

Crush: Beetlewing- Dark brown Tom with pale blue eyes and a chipped ear
Love the name! He kinda reminds me of Hawkfrost though. And more detail would be nice. 4/5

Mentor: Minnowheart- Light gray she cat with light brown eyes
Minnow is such an awesome prefix that needs to be used more. I like the brown eyes, but more detail! 4/5

Best Friend: Echostream- Dark gray she-cat with light blue eyes and a scar going across her flank
Could you please explain the prefix 'Echo' to me? I've never understand why people use it. Is it because dark caves echo? Usually I see it used for black/gray cats sooo.
Also, guess what. More detail. 4/5

Backstory: As a kit, her mother ushered her into being a medicine cat before her parents spilt. She decided to go on as a medicine cat apprentice because she didn't want to upset Swiftfern. Spiderstar asked her tons of times before he actually announced that she would be the next medicine cat of RiverClan. Her sister Tumbleberry wasn't always the nicest cat or easiest to get along with. Echostream is her best friend she knows she knows her secret. As a new apprentice, she was always mooning over the older apprentice called Beetlepaw. When she got her full medicine cat name Beetlepaw, now known as Beetlewing started to actually notice her, and they started to hang out.
The first thing I want to say, is it's a bit short. She's still an apprentice, but their could be more detail to it.
Like how did she meet Echostream? Why did they become friends? Why did Beetlewing want to hang out with her? Also, why wasn't Tumbleberry nice? Was that just her personality or did she not like Maplebelly? I'm glad her dad seemed to care about her, but it sucks her mom was one of those types. 16/20

Total: Your total is 84/105! Not a terrible score, but certainly show room for improvement. I like her overall character, but there are some things lacking, most notably in the backstory, personality, and description. All I can say is DETAIL. Go crazy with detail. Knowing every insignificant thing about your character makes them a lot more believable, even if your not giving all of it on raters like this one. To end on a positive note, I think this Oc is one of the better ones. There's lots of potential in my opinion.
