I read the first few chapters of your story!
I think the biggest tip is to edit, edit, and edit, particularly with grammar. Readers tend to pass on the story if there are a lot of mistakes.
There are misspelled words, words that are capitalized that don't need to be and vice versa. I suggest Grammarly since it gives automatic suggestions to fix 
Example: I see 'blood' a few times, but I think you meant 'blonde'.
The tenses change a lot. Sometimes it's past tense, but then changes to present tense. I find that it's easier to focus on past tense!
I'd also really focus on the grammar in your dialogues.
Can I make a suggestion from your chapter 1?:
A young girl comes running down the stairs. She has blond fluffy hair and wide blue eyes filled with energy. She wheres a red pair of squarish goggles along with a light blue hoodie and dark blue jeans." hey mom, oh, do I smell pancakes?"
Lexy said ecstatically and she began to help set the table for breakfast and once done she sits down to enjoy the pancakes her mother made.
.................(I skip some paragraphs here)
Lexy breaths out in frustration "but what about regionals? you had promised that if I made fifth place or higher on the last archery competition you would take me. I, made, first and what about the shooting range so I could practice with the rifles?" the blood grits out in anger.
Next, I kept your tone but altered a lot of the grammar:
A young girl ran down the stairs. She had blonde, fluffy hair and wide blue eyes filled with energy. She wore a red pair of squarish goggles along with a light blue hoodie and dark blue jeans.
"Hey, mom-oh, do I smell pancakes?" Lexy said ecstatically. She began to help set the table for breakfast. Once done, she sat down to enjoy the pancakes her mother made.
.............
Lexy breathed out in frustration.
"But what about regionals? You promised that if I made fifth place or higher in the last archery competition, you would take me. I made first place! What about the shooting range so I could practice with the rifles?" the blonde grits out in anger.
Alright, so this version is my writing style:
A teenage girl in her rebellious phase hurried down the wooden stairs. Each step creaked from the weight of her thumping feet.
Lexy's blonde, cheerleader-esque hair whooshed behind her, although a couple of strands stuck to the corners of her Chapsticked lips. The energy that was ready to face the day flooded her ocean-blue eyes, but it was difficult to tell from behind her boxy, fire-engine red glasses. Today's chosen outfit consisted of a sky blue hoodie and indigo Levi jeans.
"Hey, mom! What-oh, are you making pancakes?" Lexy ecstatically asked.
The kitchen was in a tornado disarray from her mother's rushed cooking. To help, she gathered the plates and silverware from the cabinet for their special breakfast. Lexy placed the forks and knives accordingly, eager to start cutting into the homemade flapjacks.
...............
She huffed in frustration and thought, Are you freaking serious?
"But what about archery regionals? You crossed your heart that if I placed fifth or higher in the last competition, you would take me. I exceeded your expectations and made FIRST! Also, what about the shooting range? I was supposed to practice with the rifles, you know." The last part was laced with obvious exasperation.
I hope this helped! Editing is my least favorite part of writing my novel, but it's a must.
