What Do You Think About The Idea for My Novel?

This is a little something i'd like to share i want to become the next big author i know alot of people say this but i believe i was born for this purpose to give birth to a fiction series now a couple warnings my literary skills only take affect when i professionly write most of what i write for my novel series are with no misspellings or poor grammar i check what i write but online it is far different so do not let that disceive you anyway my idea is about a boy named Phoenix Striker he is no ordinary boy he is a half-demon in another world these demons are like you hear of they don't come from hell or fight against angels these demons share enhanced and similarly demonic abillities such as enhanced speed, senses and agility to conjure blasts from their fists and some even transform into a "True Demon" which is to change eye color to red to grow wings to grow hair, etc but these demons are not common in every generation anyway there are two sides of the land of demons who have been in conflict for over a decade who have developed armies the east side known as the side with the most morality or good for short the non-civillains named Knights and the opposite on the west side and non-civillains named Phantoms the timezone is lost as there is modern day electricity and internet but no automobile transition the combat is more Medieval the main weapon in the series are Swords the land or map shall i say is also more Medieval and a cross between some modern day architecture the story simply runs on a Prophecy "Only one of the striker's blood will eradicate the terror that locks itself within the menacing body of seed." meaning only the two surviving blood of the striker family will defeat the main antagonist seed who betrayed the main story's village 12 years ago, responsible for the death of the striker branch and ofcourse the title of the series is named Phoenix Striker For a reason so it dosn't give away much thinking to who the prophecy will be fulfilled by anyway for anything extra series planned for 7 books time gaps included races introduced abillities increased character developed takes a huge hit mind boggling in depth-story you get the idea i didn't want to mention too much for when i take the challenging road to the world of publishing to spoil it this is just the idea and beginning plot i have to hopefully make this almost as successful as harry potter or other world famous fiction franchises so mainly what do you think?
