Most of the positive comments I get are about the story and characters, and how well developed they are.
I've also gotten a lot of 'thank you for creating a character like this' type comments for some of my characters, mostly for Hannah, Osiris, Andrew's Dad, and Lorelei's parents.
I get a lot of 'thank you for saying this' 'This is a powerful moment for me' in concerns to dialogue and story.
Art wise a get a lot of complements on how clean my lineart is, and how noticeable my improvement is (which is nice considering how bad the series started because I was fighting with arthritis when starting it) They like how I draw expressions, and how the layout though simple is really easy to read.
A lot of people happy that it's a daily update comic.
Lots of comment on 'The feels' and how they can't wait for me to rip their hearts out.
