I'm from Croatia. I've been told that I tend to use slavic sentence formation in English and vice versa. However, when I edit text I have no issue finding mistakes :)
I will post a short story writing practice later, but I'm not sure about freewriting as my daily life is quite repetitive :) (Maybe I'll share some dream journals)l
Edit: I did a bit of a freewrite rant recently, but it's probably not worth the reading time :)
