Read it over and I have to say, it's quite good. The story is unique and the dialog is engaging, entertaining and it draws you into the conversation. There are some slight spelling and grammar errors but nothing that's too drastic. If anything, I'll mirror Lux by saying that you should attempt to mix up your vocabulary a little more. Also your smack talk does come off as a bit aggressive as well but perhaps, that could be played off by switching Arthur to be more of a grey scale character? Not evil and not always perfectly good. It would explain why he could go off on a tangent like that and still be seen as a hero. Just an idea. Otherwise, I'd suggest that you tone it down a tad and attempt to use more wit and guile with your words, when committing to trash talk in the future.
