I'm not an author, but I am studying playwriting in university, and this thread is basically outlining the same philosophy my professors use when we're reading each others' work in class. https://twitter.com/cupcake_sabu/status/1291173909723832323
first: we say things that we Noticed. this should be strictly an observation, not a compliment or criticism. Instead of, "you should've written it in third person" or "I liked that it was in second person" you say something like "it was in third person."
second: we ask questions of the author. instead of "you should've written it in third person" you ask, "how or why did you choose to write this in second person?" or "does the choice to write in second person mirror how the character feels out of control?"
third: the author asks questions of the audience. this can be anything from "does the second person perspective make it harder to connect to the character?" to "did you like it?" though the latter is generally not encouraged. this is where criticism would be requested if wanted
finally, the floor is open for general comments. this is where people generally take the opportunity to lay on the compliments, or bring up any other points that were missed out on in the three previous steps. so... yeah, this thread is great and mirrors my experiences in school!
