Love this idea.
Personally, I have next to no idea what separates good writing from bad, and stay in the “I know what I like” category.
This seems like a great way to learn about the technical things that affect how well a piece of fiction reads, in a critical way, but one that doesn’t come across as mean-spirited due to its application to your own work.
Keen for the next one.
I've wanted to do this for a long time but I finally feel confident enough in my own writing to actually do it!
