azurelunatic | From a comment, edited: writing improvement

Part of being a writer is improvement. Teenage writing, no matter how good for a teenager, is rarely objectively good. If someone's adult writing is the same as it was when they were a teenager, and they were a writer, I'd worry about them, even if they were an exceptionally gifted teenager.

I have a novel in progress,

ectogenesis. I started it when I was 14. I had a good idea, a good start... but my writing still sucked. But I worked on it, as it was the best that I was writing then. And through years of working on it, my writing improved to such an extent that I was able to go back through it and say, "This shit sucks! I must replace it!" and go through with the red pen, marking up sections to delete whole, marking sections to rephrase, marking up sections that need to be moved and changed, marking up the odd thing that can be allowed to stay almost as-is.
