"Lumi was born in on the streets of Finland to a young she-cat named Valo (Finnish for “Light”). Lumi had no siblings, and struggles to survive with her mother, eating scraps of food from trash cans and catching a mouse or two."Firstly, you should just have "in" or "on". But I'm pretty sure that was just a typo. You also switched from past to present tense, so you should change "Struggles" to "Struggled".
"But then, Lumi decided that she wanted to more than just sit in the streets, eating garbage and scrawny creatures. So her and her mother decided to go into the forest, which was mainly a vast expanse of pines."Lumi didn't want to sit in the streets? You should explain that Lumi told her mother that she no longer wanted to live there and that's why they moved. Also, "more than sit in the streets" should be "more than to just sit in the streets".
"When Lumi went hunting the next morning, a fresh thin layer of snow had fallen over the pine needle covered ground."This would be better if it was "When Lumi woke to go hunting the next morning". And it should be "fresh, thin", you need a comma if you're using two adjectives. You also need to use a hyphen between pine and needle, or else it just sounds like you forgot to make needle plural. So it should be "pine-needle".
"“Who are you? What are you doing her?” Said the attacker.
“Hissssss…. Why should I tell you?” Said Lumi fiercely."Should be "What are you doing her
e?" xD Also, it would sound a bit better if you put,
"Why should I tell you?" Lumi hissed with teeming fury. Or something. That, or, put Hissssss in italics to show that it's a sound effect. Or it just looks like Lumi is actually saying Hisssssss. xD
"He seemed to be pretty well fed and in good shape from the looks of his muscles."It would sound better if you put "by the looks of his muscles."
You also used yelled and hissed a lot in the conversation between Lumi and Heikko. Try some more colorful synonyms:
Yelled: Called, Cried, Screamed, Screeched, Shouted, Wailed, Snarled, Yelped.
Hissed: Snarled, Growled, Derided, Mocked, Spat, Rasped.
;3
"“What makes you think that?” She replied annoyed."She responded in annoyance. Would sound better, because you used replied previously..
Another thing is you used "said" a lot, but there are many other words that can be much more descriptive in the tone you're trying to portray. More synonyms:
Said: Meowed, Declared, Told, Stated, Implied, Huffed, Claimed, Mentioned, Retorted, Sassed, Pleaded.
"from the bitter wind"You already used bitter, try using "biting, severe, intense or stinging."
"Your used to garbage."Should be the contraction, "you're".
"I’ll show him!"This should be "
I'll show him! Lumi thought in displeasure." To show that she was thinking it.
"It ran forward, right toward Lumi. She began to run, but the do was much too fast for her, and it caught up with her."Should be do
g, Also, you should describe the fear that the characters are feeling. "Lumi's fur fluffed out ten times her original size, her clear, green eyes widening in fear. Immediately she turned and ran, sending a wake of snow after her. Her heart thumped harshly in her chest as she pushed her legs on, but it was all in vain, as the dog was too fast."
Of course, make it your's. It makes the story more interesting and helps the reader feel what the character is feeling.
"Pant….. yeah……” replied Heikko. “You have to be more alert… that dog would have killed you…”
Heikko stood up and shook off the snow and dog fur that clung to him pelt.""Yeah" Heikko panted from the emergency rescue, Again, panting is a sound effect, people don't actually say "pant" when they're out of breath. x3;;
Anyway, it's a cute story so far, I like it. The character names are very creative. Though, the story is a bit overused, so it would be cool to put in a surprising plot twist of some type. It'd make the story more engaging and exciting. I can give you more ideas if you PM me. Good luck! :3
