All your stuff is "talky"
That's your style of humor, a strong mix of obscenity and subtlety. It's unique, embrace it, see how far you can take it. I found the course of the dialog highly amusing, and the way you illustrated the characters, both visually and through their behavior, was also fantastic.
My beef was the fact that you changed the ending. I honestly think it knocked your piece down a rather big notch. I really liked having the end leave the rest up to your imagination. Having Draconius standing there looking around contrasted so well with the beginning of Gigantor doing the same. Draconius being indecisive also fit the boring character trait you gave him. The original ending really brought a full-circle feeling to the flash and I don't think it could have ended better. Shame.
