...You think I don't already know they are mimics?
Well, the way you were carrying on... yes.
It seems to me what you really care about is the art style (drawn vs. using the game's 3D assets) which was never specified by Valve, and you're starting to blur that with "originality and time spent" when it comes to how you deliver your put-downs.
The whole contest was about mimicry of two different things: TF2 and WWII. However, it's beyond mimicry to start with the original WWII poster and then paste over three small sketches and a single word of text. (Resulting in a slogan that doesn't even make sense for TF2.) I'd wager I spent the same if not more actual time into mine than that guy, even if you don't like the deliberate "in-game" art direction.

Re: "Straight-up screenshots" and "Raw screenshots":
If they really look like they came straight from the game then is that a compliment? Except from the background
none of it is from in-game, and I do not own Garry's Mod. Everything else is generally posed and composited manually from the face poser, model editor, and particle editor. (Hence the lack of antialiasing options.) You try doing the same thing and you'll discover the places I had to go in with Photoshop to fix glitches nobody notices when they're actually playing.
I stand with what I said before and even when the contest was announced: Valve didn't specify enough about what they were looking for. Ex: "Does it have to be something you can put on a T-shirt?"
