For CalypsoClover

Name: Plover

I like this name!

Gender: male

Okay.

Tribe: Mudwing

It's a MudWing! Hallelujah!

Rank: Soldier

Makes sense.

Residence: Mudwing Kingdom

Good.

Appearance:
Mostly a bright Carmel, deep green eyes, thick tail yet his tail is small. Light brown underbelly, long spikes on back that slowly go short the more down his body. Normal height and weight.

Okay, a pretty normal appearance. I'm confused by what you mean when you say his tail is thick and small. Do you mean short? Anyway, this is alright, but could use more detail. Instead of making him a normal height and weight, you could give him a more interesting body shape, which would make his appearance easier to picture. It make the character more original. Just some advice.

Personality: Arrogant, loud voice (he has trouble controlling his voice level), firm, likes when things are under his control and their done his way only. Very noisy and likes listening to gossip. Reckless, strong headed.

Okay. This is great so far, I can see the personality you're going for, but I think that you could add more positive traits. He seems pretty unlikeable at the moment, and I don't think that's what you were going for, but even if it is, mean characters have positive traits too. So, add more to this. If you can't think of any positive traits to add, you can always google it.

Also, try describing him using sentences rather than just listing personality traits. It's easier for me to understand. You could describe his interests, hobbies, and likes/dislikes as well.

In his backstory, you mention that he felt useless after the war ended, which is something you might consider going into detail more in his personality.

Family:
Mother: ?
Father: ?
Siblings:
Bark, Acorn, Landslide, Grime

Okay. It makes sense that he doesn't know his parents, since MudWings usually don't.

Backstory: Plover was a soldier during the Sandwing war for 9 years. Plover and his siblings of 4 were at the top of everyone else. Plover was the second oldest among his siblings, he didn't have the greatest relationship with his bigwings, Bark. He always question his orders and got in the way and was very reckless. when the war was over he was devastated. He felt like there was no purpose in his life if he didn't know what he was fighting for. 7 years after the war has been solved, their was a Sandwing princess named Solar. There's been fights here and there between Queen Thorn and Moorhen. Queen Thorn ended up giving the icewings half of the land blister had promised to them for peace full terms. But, Queen Thorn saw the mudwings has no threat and therefore never gave Queen Moorhen what Burn promised to her. Plover saw his chance for "honor" and ended up kidnaping Princess Solar and would return her for exchange of treasure and land in secret (Queen Moorhen didn't know). Queen Thorn blamed Queen Moorhen, she denied it and a battle was planned out between the tribes.

This is good so far. I'm a little confused about princess Solar, since Thorn doesn't have a mate, idk who she'd have a dragonet with. Though, I suppose she'd have to have more dragonets anyway since Sunny doesn't really seem like she'd want to be queen. I like that you described how he felt after the battle, but I'm kind of confused by how that led him to kidnap Solar. How would kidnapping a princess without his queen's knowledge bring him honor? And surely Moorhen would be angry with him if she knew, because she was blamed for the kidnapping. 

Also, this backstory just kind of.. ends. I know you said it wasn't finished, which I understand, but I'm curious. Do they go to battle? Does Plover let Solar go? What happens after that?

(I'm sorry, his backstory isn't finish, I've just recently developed him and I sought for your help because I know your a good expert with Wings Of Fire OCs so I wanted him to be ranted before your forms closed)

Okay, I understand. He's okay, but could use some work. Sorry if you felt rushed to get him in on time.

Overall
I give Plover a 4/10. His appearance could definitely be more detailed. Personality is good, but could use some more positive traits, because he just seems all negative. A good personality has an even balance of positive and negative traits, not all one or the other. His backstory is also alright, but seems unfinished, and a few things aren't really explained. Overall, he's okay, but I can tell that he's very underdeveloped.
