Okay taking a look at it, he's got a point. There probably should be a little more emotion and backstory in there. It also feels like a bit of a Mary-Sue fic. But you kind of are stepping out of your comfort zone. You're willing to go into someone else's point of view. It's true that writers are kind of the way he ays but they write in their comfort zone too so you're not the only one. Post A Mere Raindrop and other backstories and let Josephine become a bit of a background character or show her flaws a little more obviously.
I wouldn't leave PC over this. I'd look it over, be grateful the dude has time to point out some flaws, and keep on stepping. No offense. Then again you don't have to take me seriously as I've prefer people dismembering my stuff. Every now and again you'll get those reviews. Just take what you can get out of them and make things better.
I can't. AIM won't even let me IN. Keeps saying my name or password are wrong. I'm like "I don't think so!! I know they're right, I've been using them long enough!!"
