Great work again...
Pros: These episodes keep getting better and better. It's refreshing finding something with an actual plot rather than a pointless animation because in my opinion half of what makes a good flash is a good storyline. The fact that you took something that some many people love and put your own twist on it is awesome. Great job with the animation, the 3-d animation was superb as usual. The 3-D hydralisks and zerglings looked great way better than in episode 2. I dig the music, especially the guitar solo one during the space fight.
Cons: Here's some constructive criticism for you. During the hydralisk/zergling battle, it seemed the amount of gore was lacking. I mean, even in the game they blow up in a bloody mess. Remember, this is a starcraft tribute, the least you could do is create that same gorey likeness. In fact, the only blood I really noticed in the movie cam from the ghosts mouth when he was battling the zealot in the beginning. Another flaw I noticed with the animation was the amount of lip movement. It seems you got a little lazy with that seeing how the viewers don't see lip movement until scene 4. The sound quality was nice but the voices still need a little work... something seemed missing... I'm thinking maybe a variety of different sounding voices and possibly a girl voice (medic, valk, or dropship?). Think of how different the voices sound in the actual game and compare that to your movie.
Over all, awesome series. I put you in my favorites. Thanks for doing this I was waiting for someone to do a starcraft tribute for a long time. Keep it up the good work I can't wait to see the next one!
