Well developed.
First thing that struck me was the lack of color; it was rather Sin City-esque and it was quite captivating. I must say, you've outdone what I expected when I clicked onto this flash. You've combined a good although albeit somewhat generic monologue with a brilliant musical score and fairly fluid graphics to make something surreally excellent. Even though there's been a sort of "wrongdoing masculine figure with a good heart where it counts" theme done many times before (or maybe I just watch too many movies), this really stood out and I'm not surprised that it's gotten such a good score at all. This is probably the best christmas flash I've seen so far.
What actually intrigued me the most was the comic in the credits. It was awesome to watch - kind of like when there's a behind-the-scenes storyboard special for one of your favorite television shows. The original art style was bordering on professional - do you or have you thought about being a graphic novel writer?
Anyway, great flash, truly done in a well-developed sense of composition and I can find no fault with it whatsoever. Loved the idea; the conventions of Christmas broken down into the commercial side is always a winning ticket if it's done the right way. Let's face it, christmas is mindless exchanging of money, although there is a certain mystic aura to it, mostly because of the falsified atmosphere but I can understand where your character got his cynicism from. He has that "bad childhood" vibe.
As a last note, maybe you should look at turning that character into a series. It'd do very well.
Thumbs up.
<3 Merry Freaking Christmas. xD
