The thing about writing, as with most art, is that it can't be quantified and it's difficult to qualify. It simply is. I've not read your work, but the most important thing I ever learned in proofreading or critiquing others' work is that the criticism must be constructive. You say what you liked, and then comment on what you didn't (kindly) with a reason why you didn't like it. The choice of subjects is never something you can critique. If you don't like the subject matter, don't read the story.

I'm a writer myself, and I would be as hurt and upset if someone ever flamed one of my stories. I know I have a tendency to overwrite and overdescribe, and I've gotten some useful feedback on that. But "constructive criticism" are the two most important words any reviewer should know.

P.S. Oh, and I've never critiqued someone on spelling when it's obviously British English. To say that either Americans or Brits are "spelling wrong" seems to me to be on par with saying the Chinese alphabet is wrong. It's not wrong, just different.
