As someone who has a diverse heritage I still feel people would like to know if they have made a major mistake that could confuse their readership. I am totally in awe of people who can write stories in a language that is not their first language! BUT I assume for that very reason that they wouldn’t mind some help. If I was writing in my mothers language (which is my first language, but , local, schooling etc overtook it)
I would welcome constructive criticism .
