Thank you, you made my day. I spent way too much time reading commets in HN, and that effort paid off. :)
Of course! Coming from someone who's tried (and failed) to learn a bit of Mandarin, even the spoken language was quite tough. Chinese/Japanese/Korean -> English/Romance languages is quite a tough lingual gap to bridge, and you should be proud of yourself for achieving fluency!
Maybe the thing that most sticks out to me is saying "English writings." I don't think a native speaker would say writings, just "in their English", or perhaps "In their written English."
Your English is fantastic, this is me simply musing on what you're suggesting.
