I need your advice/help/kick

Ladies and gentleman! Furries and scalies! I'll try to be brief.
I working on the story that can't just leave my head. I named it The Lilac Valley. A fantasy story about dragons, filled with love, tragedy and magic. I'm trying to work on it, but my primal barbarian nature in panic, and i can't decide what i should do next.
All my works is always an improvisation: spontaneous thoughts are comming to my head, i describe it, but it need to be consistent. My thoughts are racing from side to side, and i think i need a kick from people. I decide to ask cumcommunity. I'm asking: What would you like to see?
I have a several ways to go:
Actors means nothing without the scene. Do a worldbuilding. Tell what this valley is. How it looks, geography, flora and fauna.
Actors is a life of the story. Do a characters first. What they love or hate? How they are looks?
Do your research. What is the point of your story? Take a pause. Read smart books and comics, watch films.
You already created Fleily , first of all you must work on her.
Fleily is the main character, and i have some small notes about other characters:
Metfar - a Fleily's brother.
An azure dragon with red lines along his body. A bully, a slob, a funny guy. He likes silly dirty jokes and strong women. He considers it his duty to protect Fleily from all harm. Big brother in one word.
Vismyca - a Fleily's companion.
A green scaled dragoness from wild tribes. A simple girl with the soul of a warrior. Grumpy, always on alert. Knowledge is power. But if you have the power, you don't need knowledge.
Fercultirax - an empress of a dragon emipre.
A mighty dragoness with red scales and four wings, whose strength and refinement are matched only by her ambitions and conceit. A pragmatic and cruel ruler. Her anger is like a hellish whirlwind, that burning away everything in its path.
The unknown one
Half dead half live dragon. His living half is skinny, with faded scales and a sinister red eye. His dead half is blacker than black, like a gaping hole in space leading into an endless void. The pure evil. A sadistic, smart and tricky creature. His mind is his only positive trait.
This is a incomplete list. Just a couple of thoughts.
At weekend i'll begin to work like Geppetto. And hope that i can show you something at christmas. Thank you for your attention.
Chill.
p.s. I'm sorry for the lexical and spelling mistakes. I used google translator.
