Stop writing a bunch of questions, no one is going to deliver you perfect answers or serve everything in a golden plate for you.
Back in my days the only thing you received as an answer was "Practice" and the rest you had to figure out yourself without asking further because that's all you were allowed to do and then YOU had to WORK, actually getting YOUR HANDS into drawing or writing.
Your story is going to suck, like anything anyone finishes for the first time because guess what? You are an amateur, a novice, you have no real experience and for as long you don't have experience you won't improve. You can complain, asks a bunch of questions, be a petty little individual making a bunch of excuses and counter arguments but to be fair theory is totally different from practice, you can try to plan and get as many answers but they'll be all useless once you start to actually work on your series, continue working on your series, advancing and solving stuff as you go and you'll only get your resolution when you actually finish something, actually have a product to analize and improve.
You focus way to much on your ego, I see a lot of barking but no actual biting.
People tell you your character is going to be one-dimentional? Instead of arguing back, then fricking write your character and prove if it can be more than one-dimentional.
Lots of talking, lots of replies but I don't see work being done around here, and even if you came show it I couldn't care less because I'm not interested in reading whatever you make because the few things I've read sounded like the most generic story made by a teenager who thinks this is their magnum opus, they are going to be so popular and be like 10 years publishing their series, having big ass chapters and volumes and wanting to be the next Eiichiro Oda.
