I voted Grief because it doesn't matter how well drawn your comic is. All that matters is how you connect to your audience, and that was the one that genuinely entertained me.
Ilaekae / Everyone - if you want this to read the way it would in print, put your spreads side by side, and add an extra linebreak between pages vertically.
Arttorney - I'm assuming you want honest crit, and so I have to say yours is painful. I see from your website that you can actually paint, but your digital work, especially drawing with what I must assume is the mouse, has a long way to go, and your layouts are more avante-gard than dramatic. I'd try using traditional media (or, since you're into geometric shapes and cubism, maybe something more geometrically stylized -- see for instance http://drawn.ca/2008/01/03/bob-staake-in-real-time/ ) and go for simpler, visually clearer layouts.
Flip - the story is pretty random, which makes it hard to evaluate the storytelling. Be careful making major scene/time changes between pages -- even though it seems like a logical place to do it, the audience can get confused, thinking they missed a page, if there isn't some cue as to how the new scene relates to the previous one.
Grief - I love it. You have lived by the maxim "know your audience". The ending is sudden, random, and a bit sequentially confusing; but it doesn't matter in this genre, all that matters is how many laughs you get.
Gwenevere - I like the linework, and the flow is clear. I think there are some slight problems with the legs and feet on page 2. Your panel shapes are pretty cool, but I find them a bit distracting, and they also leave what I would consider an excess of white space. This may just be my particular taste. Have you studied the panel layouts of some of the manga masters (Shirow is my fav)? They frequently use wild shapes in their action scenes, but they keep them pretty snug and don't overlap them very often.
Joe A - I'm not crazy about the way you're using digital here. It almost looks like a 3D-rendered background, which IMO never works even when it's done really well. Your layouts are nice and clear. The story and the drawing are both somewhat lacking in finesse, but it's a good effort.
JonZ - Very strong piece. The first page reads a bit choppily, but I think you may've intended that. Page2 panel1 could use some device to draw focus to the main character hopping in his car. Page 3 last panel might work better if it was less similar to the previous panel (zoom in closer, perhaps). Page 4 might be more dramatic if we got to see, for instance, the frightened driver, but of course that might be a little tricky to fit in. Overall excellent work. Great FX.
Sinix - I love the style. Clarity could be better, especially at the end.
Skorpi - Overall nice work. Good camera angles on the first two pages. The last page looks rushed, and the last panel, between the rough drawing, plain camera angle, and bad tone effect, ends the piece on a clumsy note. On page 2, I don't know why he looks over his shoulder or what's making the "KLIRR" sound.
Stoat - Very nice piece. It took me a while to match the locket/medallion in the closeup to the one she's wearing in the long shots. I'd recommend you change one of those three closeups to a medium shot where we can see at least her lapel. It also took me a while to decipher the final reveal of the IV bleeding out on the floor, but I'm not sure what the best way would be to make that clearer -- maybe have her touching the IV line? Also that last page composition might be more dramatic if you used perspective.
Zeitwolf - Your story doesn't really have any emotional hook, and is a bit hard to follow. I actually think the concept is clever, if I'm reading it right, but I think you need to spell it out a little more. The bottom row of panels on page 1 is too long -- that middle panel isn't doing anything except breaking the rhythm. Your camera moves in the sword-slash sequence are too broad (you basically reverse angles 3 times) but yet not very dramatic because you stay at eye-level. A longer shot would be clearer to show the shapeshifter knocking away the guy's sword, and a reaction shot of the guy would really help after that. As for the art, it's obviously not to the same level of finish as most of the others. Which is fine for learning purposes, and anyway I wouldn't invest a huge amount of time rendering something until it reads well.
Hideyoshi - Your piece was totally pro. I'm guessing maybe you didn't want it in the poll because you *are* a pro (though Ilaekae messed up by including your name)? My only complaint about it is that it's too perfect an imitation of Otomo's style.
