Alright, i need some help, some motivation.

My original work is called Smile or Die. Its about the epic struggle between two race of beings (that i made) the good race is the Moon Beings. and the second is Earth Demons. Both only have 1 survivor left, and the Moon Beings have something to hide. Which get us to the story. Van Moonflow is the Guardian of an artifact that makes you a titan, but he doesn't know it. Sora Silverglow is the last Earth Demon and his race has been trying for thousands of years to get that artifact and earn their place beside the Gods and Goddesses.

Van Moonflow is Eighteen years of age and 7'2" and is very skinny for his height. >.< such is for all Moon Beings, but he thinks he's a freakish human. His eyes are purple with a white crescent moon in the pupils. His father killed two days before his birth and his mother died a few days befre he turned eighteen. he graduated high school. not much to say but he became a bounty hunter and the biggest bounty is the villain of the story.

Sora Silverglow is over 3 thousand years of age, he's been all over the would and made his residence in Haven City where Van lives. He's the villain and has been on a murderous rampage killing without mercy anyone who steps in his way. His two hentchpeople is Kal Desertice: a active outcast of her race of animal. half snow leopard and half lynx, she's a bi-pedal animal like most of the people of Haven. and Bobo Ironfist: the stupid, dumb muscles and a half human and half elemental.

The artifact is a Moonflower pendent made by the gods to get the Moon Beings closer to them. When activated the pendent gives the user the sense of purity and enlightenment, along with ultimate strength and mental power. the cost is your voice. The pendent has a secrete power that has never been recorded. that is it purifies anything evil that touches it. it can also Teleport the user to any location in his mind.

the titles is about a few things. 1. The villain tells worthy oppenites that. 2. its an awesome and mysterious saying. and 3. its about evil and goodness breaking their deal and fighting each other. its either you Smile (go for the good side) or you Die (go for the evil side).

now it comes down to this. I need motivation, and ideas for it. There are other characters for this story. Geno Greenleaf or Yo-yo is a plant, with red eyes, pale skin and purple hair. this anatomy is different from most creatures. he uses either the human source of living, or photosynthesis. or both. he doesn't have to eat, but he must have water. there are flowers that grow from his hair and is part of his blood system so they put sugar into his blood which is his source of food. his father Jake Greenleaf, his sister Rose Greenleaf, and Martha Greenleaf, his mother. there is also Mammoth Heavenbreaker. a pure Earth Elemental. his size makes him worthy of his name. his hair is a moss color and short, also when angered he rages and turns into a mammoth and can't control himself. Zoa Cross is Van's partner in the bounty hunting business. and they hook up in the end.

So yes, please help me. i'm open to all ideas to make this story better.
