A potential crit partner returned my chapters with comments about the story itself, which I appreciated, and lots of line edits, which I didn't. IMO, when another author rewrites your words, they've gone too far.
So how do you approach a critique? A few guidelines come to mind:
RESPECT the author. The purpose of a critique is general feedback, not editing. Note what you like and what gave you pause as far as plot, characters, and setting. If you see grammar and punctuation errors, point them out and move on.
Some responders claim they don't know how to tell the author what's wrong with a given section, so they just write it out for them. Seriously? If you don't know how to phrase your concerns, it's time to Google "constructive criticism" and learn the basics.
RESTRAIN yourself (see above). It's not your story; don't presume to fix it. Yes, you need to address areas that concern you ("I'm confused here" or "Not sure if this is the best way to transition" or "I didn't connect with this character", etc.). Leave it at that. Let the author consider your comments and choose whether to act on them or not.
REMEMBER, unless a specific request has been made for editorial feedback, all anyone wants is your opinion. Share what worked, what didn't, and let it go.
What's your take on this?
