Which comment would be MOST useful as feedback on a flash fiction story?

Question

I wish the main character had been a boy instead of a girl; it would make more sense.

Your story is too short to achieve its purpose--it should be twice as long.

The ending seemed a little too vague about the surprise it is supposed to describe.

Can you replace the main character with someone who is more likable?

Answer 1

The comment that would be MOST useful as feedback on a flash fiction story is:

"The ending seemed a little too vague about the surprise it is supposed to describe."

This feedback is constructive and specific, focusing on a particular aspect of the story that can be improved. It allows the writer to understand that the climax or resolution needs more clarity without imposing personal preferences unrelated to the story's intent or themes.
