Here is the second installment. Expect them to embark on the city in the next one.
As I said before, drawing without a direct reference is difficult. It has caused me to really study several other cartoonists (Jeff Smith, Craig Thompson, Mike Mignola, etc) and taught me that the gesture is sometimes more important than the proportions of a figure.
I also noticed that the "jawless" zombie in the last episode had a "more than stylistically off" nasal cavity. He looked like a k-9. I fixed this and re-uploaded the image.
