...and there's the problem. You seem to refuse to take any feedback or criticism so your script and skills never get any better.
Placing in the top 317 out of 800 scripts in a contest puts it just above average for the scripts submitted. It's still worlds away from being picked up by Hollywood.
In running terms, that would be like placing 317 out of 800 in your local turkey trot. Would that be grounds for thinking someone was close to a professional level? Not even close. Especially if they have been training since 2011.
The average marathon in the world last year was something like 4:25. So 4:15 is above average. That's what your script is. A 4:15 marathoner.
Would you tell a 4:15hour marathoner that they have pro potential? That's probably why you get some flack on here. It's a bit like a 4:15 marathoner or 430 miler telling us over and over that they know they are good enough to go pro.
Don't tell people. Show people.
The next step is to improve to a professional level. It's great to have a complete script, but the odds of it getting picked up by a studio are about the same as the odds of Nike signing a 4:15 marathoner to a pro contract.
If you are truly as passionate about getting it made someday, you need to take some constructive feedback and seriously work on your writing and story telling skills. You should be writing a complete new script every 3-6 months. That's what it takes.
You mentioned in your youtube video that you don't really consider yourself a writer, that you don't have any training in it, and that it was basically just a means to an end in order to get the project made. Well.....the people who are winning these contests and getting their projects made don't think that way. You are competing against people whose entire life is writing. People who wake up and write everyday before work. You seem like you want to get a movie made, but not do all the actual work and steps required. Becoming a good writer is one of those steps.
Imagine someone saying they wanted to make the Olympics in the marathon and were really passionate about that goal, but they had never trained and didn't really consider themselves a runner. That they really just ran because it was a requirement to get to the Olympics.
What do you think their odds of reaching their goal would be?
I don't mean to dismiss the effort it took to complete a script. Most people don't make it that far. So, congrats on that. But if you seriously want to see this project succeed, it's important to be realistic about where it's currently at and how much work is needed to reach your ultimate goal.
Otherwise, it sounds a lot like a 4:15 marathoner talking about how sure they are that they are going to the Olympics.
Best of luck.
