Art.
The art was excellent, definitely true to the original.
The voice acting left something to be desired. One thing that's really odd to me is how incredibly faithful all the parodies so far have been to the original tankmen voices, and I can see why, the voices are really integral to the humor. Although I could hear you guys were trying, and it was pretty close, poor sound quality really took away from the effort.
Finally, some of the jokes just fizzled. For example, when the guy said 'Enemies? Like, people who want to kill us," you had a great set-up for some kind of joke, but you totally wasted it. The next thing that dude did had no relation to that quote; it made no sense. It's true the other guy responded 'We're gonna die,' but it didn't really exploit the setup very well. Having set up the first guy as a total idiot and a coward, you coulda had him try to fuck the tank's tailpipe one last time, or maybe turn and run smack into the crazy knife guy's knife, or something. Anything.
Sorry, I know that's a lot of criticism. Truth is, overall I thought this was pretty good. It's just it was close to being really good, but no cigar (cock joke). Recommended for teh collection.
