Wow!
That was truelly amazing. I loaded up number 3, but decided to begin the series from the first since I never saw them. The first started and ended with such little plot. I was interested, so went to #2. Deffinitely an improvement, more plot. It showed the struggle.
And now, the 3rd installment. Fantastic! The scene where she is on the ground wrestling the creature, was really gripping. Your animation is awesome, and your sound is great. The feet I would suggest be a little more.. flexible. How they remain so stiff kind of creeped me out.
But holy hell, can you draw zombies (and guns!) awesome. Very nice work. I would just say work on the feet a little and maybe throw in some reasoning. For example, how did the zombies come alive? How did these 2 seperate? How are they in relation? Things like that.
Very nice job. Very, very nice.
