Nope, my first language is Italian and English is my second! Still, I write the comic directly in English because I find it easier compared to writing in Italian first and then translating it, especially when it comes to puns (which would be nearly impossible to translate anyway)
As for other languages: I can read/understand spoken French 'cos I studied it in middle school, but I pretty much forgot everything about writing it. I also have some VERY basic knowledge of Swedish thanks to University + some self-teaching
