I do make comments about the content of the story such as, 'wow, I can see social services getting in involved with this family, I believe that mom went a little overboard, Well, I don't particularly like a father spanking a teenage girl's bottom, etc... However, I don't make comments about the writing. That's not up to me. The LSF has a nice write-up about that.
Comments about the writing are what I would want to hear more than anything else, and far too rarely do hear. I want to hear what parts seemed particularly effective, and what a reader thought didn't work. If a PoV Switch was confusing, or a flashback seemed out of place, or a change of scene was awkward, I want to know. I may not agree, and I may well not make changes even if I do agree. but it will surely stay in my mind for future writing.
