Oh heavens! I'm sorry I've been absent the past while! I'm going to try do the review of @TheFireDragon work now Better late than never, I guess!
Anyway, here it goes!
First off: I think the technique, so far, is fine! I'm going to separate your writing into two categories: style and diction. Your style defines how you choose to reveal the story you're telling, how you tell it, what the story is. Basically, the content of your story. Your diction is the words you choose to tell that story, as well as your technical grammar.
I think your style works very well, so far! Your opening line was killer (aside from needing just a bit of parsing down to make it more punchy). Overall the first chapter was intriguing, with strong mysterious content. Despite some of the comments before about being confused? My answer: who cares! This is your opening. Confuse your reader. I used to hear comments all the time during novel classes that all should be clear and up front in the first few chapters. This is how you kill the life out of your story. Keep doing what you have been doing. It's very interesting and unique in a way that works.
Your diction, on the other hand, could use a few more editing passes. There are moments of wordiness that steal the punchiness out of what you're writing.
For instance: your opening line: "It was three in the morning, and it was terrific as well as it was terrifying." I love this line, but it could be reduced to: "It was three in the morning, and it was terrific. It was terrifying." or something to that effect. Though, take this advice with a grain of salt.
I hope this answers your first question. It also likely answers part of your second.
Again the intriguing part of your story is the mystery of your character's ego, and his actions. His history seems to serve both of those, which is also interesting. As far as main characters go, he's very amusing and fun to read.
I know you also asked about dialogue earlier, and I have to say I really enjoy yours. It flows like real dialogue and gets to the point just as well.
As for your third question, I see that this question comes from doubts in your own writing ability. Trust yourself. I wouldn't write this any other way. Partly because this story is uniquely you! I wouldn't know how to write it. But so far, you have all the elements of a great YA tale. One that I would probably actually buy if it were on the shelf. So, keep at it, and just keep working on polishing your diction.
Godspeed, my friend!
