I think the best mark of a practiced writer is knowing the healthiest diet for your story. Some need more fiber, some need less. One of the wonderful things about creative writing is that it's difficult to quantify, arguably impossible. So a practiced writer should be able to comb through the critiques, the self-help books, the blogs, and the forums; then decide for oneself what does and doesn't work for their writing.
I like to think I'm fairly good at taking advice that I know will improve my work and passing over advice that won't. There's always room for improvement, you don't need to (and can't) please everyone. It will only hurt your progress if you assume either everyone knows what's best for your story or that nobody does.
My last blog was how every major plot point requires some prior allusion. A patron of r/writing, arkanemusic, pointed out that sometimes one can forfeit the foreshadowing for a certain kind of shock appeal; albiet carefully and rarely. When you're comfortable with your voice and style you can forego the unofficial "rules" when you feel it'll bring a unique advantage to your work. Not something one should do lightly, but not something one should be afraid of.
