I honestly couldn't get into the story so I won't comment much on that.
I was under the impression that you were submitting this written piece to the contest and, if selected, it would be given to an artist of their choosing, not yours. I don't know about this particular contest but if you are just entering as a writer that is how I thought it worked. In that case, you'd need to be as clear as possible so that whoever is working with it knows what you're intending.
Since English isn't your first language and the script you've shared is rather poorly structured and grammatically flawed, I would focus on getting that in order first. Find an editor to fix things up or work on your English skills. Again, I don't know if you are planning on submitting the script itself or a finished comic to the contest (if you are sending a whole comic, it would be far more helpful to us and to you to post that instead of just the script). If it's just the script, you have a lot of work to do.
The language was a bit of a barrier for me, but right off the bat I found little to be engaged with. It seems like a standard regurgitation of action comic elements with little else going on. It's clear you have an interest in action comics, but what do you feel this particular story is adding to the genre?
Ok I know it's really generic but that's cause I knew it could win. I've looked over past winners and they where generic too.So what I want to do is win, get into shonen jump, then write what I want.
Honestly I'm not the biggest fan of the generic stuff they have like Naruto, Bleach, and One Piece. I'm more of a fan of they're complex manga like Rurouni Kenshin, Death Note, and Enigma.
So I hope you get it.Write what they like 1st,then write what I like later.
I know it sounds kinda pathetic.
