You're right, it's a rough draft, and I don't see the point in changing that a year or two later.
Anyway, you're right, it still is amateur. That bothers me extensively. I think that I'm good enough at writing to know that I'm doing something wrong, but not good enough to fix it.
As for your character study, it's actuallly fairly accurate. There are a few mistakes probably due to this having been the only story you read. Also, you seem to have a fairly negative opinion of Phinehas' ability to view his motives and nuances objectively. Although that's definitely true, I'm not sure it's quite as black as you paint it. I think a lot of it comes from him trying to be calloused and cynical, but not being able to help the fact that every once in a while a bit of humanity shows through. Anyway, if you want, I can dissect and enlighten your character study, but only if you want.
One major thing I need to point out, though: You seem to think that Tybalt is the tavern owner. He's not. Kada was at the time. So when he speaks of Tybalt, he is actually speaking of a close friend, not of some bartender.
All in all, though, I'm very impressed. Although I know, and always will know, Phinehas better than anyone, you've done a better job than I probably could at diagnosing his various personality quirks. Bravo. I do so love good analysis.
edit: On a less serious note: Did you enjoy the read?
