All right, I was given the green light. Here's the full sprite sheet for Mom, including with and without the little laser addition to her sledgehammer. Note: you are not allowed to use these. Look but do not touch; they belong to myself and Savant's label.
I also made a few still-frames from the cutscenes, shown here.
We had a month to make the video, from concept to completion. The actual sprite phase only had 2 weeks. Needless to say, we were crunched on time, but overall it came together quite nicely.
