You're not harsh at all either!! Massive kudos to you for being so open to constructive criticism <3 (also, kudos for the best profile picture on this website)
My only further response to your response is to bring up what you said about using healing from trauma as justification for characters' actions. As a complex trauma survivor, I think that this is bit of a shaky line to walk -- trauma is not ever an excuse or justification for negative/antisocial/abusive behavior. Abuse, manipulation, aggression, et cetera -- while they are common responses to trauma -- are never justified responses. I think that it's completely reasonable and even admirable to want to display realistic (i.e. sometimes maladaptive) responses to struggle, it's important to also not put forth a narrative in which those maladaptive responses are portrayed as healthy to readers and characters. Of course, I'm not sure what your intentions are, but your wording stuck out to me and, just in case, I wanted to provide my perspective as someone who has dealt with these issues. Even if psychological trauma isn't a major theme of your work (which, btw, I'm hyped either way; you're in no way obligated to make your art any darker or grittier or more psychological than you want to!!), it is a sensitive topic that I think it worth putting additional thought into while writing. Sensitivity readers are also a great resource!
Again, thanks for much for your kind and thoughtful response! I'm really excited to follow Scout's progress -- you're a very talented writer!! :)
