I'm gonna go through this as best I can. I have done a spelling/grammar/punctuation fix-up in Australian-English, so it might be a bit different to American-English.
Melisha
I walk through the gardens my mother used to grow, now they are overgrown. She was able to bend the plants to her will; but now she is dead and no one else in our clan can do it. There has been so much blood shed since her death.
This is really good. I think it's a good way to start the story.
I stop, someone is following me. I know who it is. "Gethara, you are still ticked about who was chosen as the heir, aren't you?"
A small rat-like thing scurries up, and tranforms into my older brother. He has long bright red hair. Yep, he was ticked.
"You think?" he bares his fangs at me, most people cower at the sight of him; but me? I just roll my eyes.
This is kinda funny. Good description of her brother.
"I am eldest. I should be heir. What did he see in you, other then you are a frail woman?" he growled, towering over me.
"If I am a frail woman, why do I command over 30 war ships? Ones that could destroy yours in a matter of seconds," I said calmly, not going to please him by going off. "We all know why anyway, remember your betrothal?"
He winces, everyone in the empire knows what happened about him and his betrothal.
Once it's fixed up, this is excellent! You can learn about spelling, grammar and punctuation; you can't learn to have a good writing style.
Rojon
I sit in my late sister's room. The sorrow is still in me. That so-called warrior prince, Gethara, should die for what he did to her.
The sound of shouting and my sister's screams as Gethara killed her still fill my ears. It was the day she told him he was betrothed to her. Everyone in the empire knew he loved a Lesha, a non-gifted one.
This is a good way to show backstory.
I was the first to see the room. The place was destroyed. He was still holding my sister by the neck as she took her last breath, I ran and tried to stop him. The next thing I knew a healer was taking care of me. My sister's body was being taken away and Gethara was let free. That day I vowed to hate all warriors. That all changed when I met Melisha.
Lekeya
I quickly walk to my small cove, the mud squishing between my toes. My mother use to live here, but she was killed after I turned 100, because she loved a Sheak.
As I walk I listen for the birds I so dearly loved, but they are gone. Since the village was destroyed many animals have fled to the safety of the mountains, like many of the villagers. Leaving only the Leshas and me, A half-breed.
This gives me a ver vivid inmage of what it's like there.
I swiftly walk into my cove, listening to the water as it laps on the edge of the right side of the opening, and head all the way to the back, to the Lesha boy i found nearly dead near here. I quickly pulled out what herbs I found and mixed up what I could remember that could heal, and carefully gave it to him.
This doesn't really make sense and I'm not sure how to fix it.
Children are rare for the Kelishans, even Lesha ones are cherished. Halfbreds are unwanted. I didnt care, like me he lost his parents. I won't kill him for what he is, unlike many Lesha have tried to do. Ever since I was born I walked my steps lightly, kept my eyes on everything and listened for the slightly sounds. When I am near water I am safe, they all know to stay away from me when I am around water.
This shows very well what it's like for her.
Dezon
I wait for my uncle to come back from hunting.
My sense of time is fading, has it been an hour, or a day? The ash is still raining from the sky. The smell of burning Kelishan still fills the air, and the smell of burning meat can be smelled for miles.
Unlike Sheaks and the younger races; Kelishans are plant based life-forms, and are the only ones. Many of the other races dont know, and for a good reason. What would happen if they knew is too horrible to think about.
The sound of footsteps echo in the cave. I look at the form. It isn't my uncle. I quickly grab my tekonsha, a curved, ridged sword. A tekonsha could cut the Sheak like it was butter. As the form gett closer I hide behind a boulder and wait.
Other Notes:
Though the Kelishans are different to us, don't make them too different. People like reading about people that they can relate to.
Remember to keep the tense consistent.
That's really good! I can't wait to read more!
