Good, but could have been better.
While this may not be up to par with what Egoraptor and Andrew Dickman have posted here, but for what you have here is better than the stuff that Arrogancy, Tyler Gibb, and those motion comic authors have submitted. As for those complaining about the lip sync being off, consider watching this in low quality instead of watching the AVI file. With that out of the way...
Graphically, the artwork looks like Keiji Inafune's style and it looks better than Arrogancy's uninspired art. The character animation may be tweened, but you put them to good use along with flash gradients and 3D. However, when the bullets were fired out of the gun, they were still in their casings, which looks stupid. You need to pay attention to that because people will notice that like a really crappy paint job. Soundwise, you did a good job on the selection of music, even if it's just one song. However, the voice work is bad and really sullies what could have been front page material. Then there's the content, which is also a mixed bag. On one hand, you have a fight that moves at a good pace, and a bit of a story. On the other, there wasn't much of that story and the pace that it went could have been a bit quicker. Now, I know not everything needs to be like Stick Slayer, but slow pacing hurts story and character development. Plus, you might want to learn how to optimize your flash, because while 2.8 megabytes may be acceptable, something like this could have easily been one-and-a-half to two megabytes.
What I liked:
-Original
-Nice art style
-Good animation
-Clever use of 3D and gradients.
-Passable diologue and music selection.
-Good plot so far
What I didn't like:
-Bad voice acting
-Could have used more story development, but that's what sequels are for.
-Uneven pacing
Overall: Even though I liked this, it still needs a few improvements here and there. Here's an eight out of ten, and you might want to get Billy Cass (DragoonFenix15) back here if you continue with this series.
