Is That You Writing, Or Someone Else

I tried to write like Enid Blyton once because I love Enid Blyton books....I loved them when I was five and I still love them today. There's something very endearing about gnomes, pixies, brownies (I thought they were the edible kind at first) and also those naughty little boys having their faces frozen mid-scowl when the wind blew - mind-blowing. You remember that one? Yeah, it's fantastic and out of this world. The world could end and Enid Blyton books would still be selling like mad cakes out of the oven.
I also tried to write like John Grisham because he's really up there and I am a law graduate. I understood (sort of) all the procedures and lingos that he was using in all his books. I got all of those stuff covered. And then when I do that, I sound like a half-baked college student trying to impress her teachers and school mates and the next door neighbor's dog.
Avid readers of love stories would definitely, positively try to write a romance novel. Those Mills and Boons stuff? Yeah, you've got to try writing them....but after a while, you're afraid that you don't know enough about all those 'stuff' to write them and when you try to get it published, people will laugh their faces off.
All of the above illustrates one point and one point only. It's one thing to admire and adore people who write fantastic stuff. They write fantastic stuff because they write the way they do. It's their style, it's their thing, it's their story. No other writer, unless it's purely unintentional, should try to copy another writer's style. That's my personal opinion about coming up with written work.
We can try to step into another person's shoes and write about something we don't know but just found out about and adopt a kind of style of writing to impersonate someone who likes those stuff. Yes, that's fine because it's not really a story but it's more like....an article. Your version of it and written while pretending that you're into fast cars or makeup or cosmetic surgery.
The difference between trying to copy someone else's style and pretending to know what you're writing about is this - is it you or is it someone else.
At the end of the day, if you try to copy John Grisham's style and it doesn't come off well, you're wasting your time. Don't even let anyone know you like the author! Stay true to your own way of interpreting things and the way you write.
Just because some other writer is poetic does NOT mean that you have to be poetic. Just because some other writer is funny, or very cute or uses bombastic words has absolutely nothing to do with you.
You're you and you're the writer. Write like YOU are the one writing it and you'll be fine.
