No, being sixteen is absolutely fine. We have younger members who do shit and do great. Really, all we require is hard work and effort. Finish your story before publishing it, we'll do our best to criticise it and encourage you, if you actually put in the time. If not, you'll be shit on.
Don't blame the issue on your age here, dude, it's disingenuous. Blame it on your laziness and unwillingness to actually do anything.
