Does Zayne's progress seem natural? Are his developing feelings for his master believable? How do you feel about his master? Memory jog for other characters: Sal, lady who rents them the room.
You don't need to address every scene if you don't feel it's necessary. If you want to, that's wonderful. However, if you just want to focus on those that worked particularly well for you (or those that didn't), that's fine too. Here's a little memory jog of what happened: Zayne sees his master chopping wood, meets with Sal to discuss, Zayne proactively begins cleaning the whole house, Master eliminates a target/Zayne spends some time outside thinking, they fall into the pit, time in the pit/servicing his master sexually, escaping the pit, lady's house/beginning of bath scene.
Natural/Unnatural? Any favorite lines? Any that you disliked or thought were out of place?
Is there enough description for you throughout? Too much or too little anywhere?
