Yes, I loved that it was from an overseas perspective. I was just talking with a family member about how non-Americans must view us on Black Friday, so it was neat to see that here.
I noticed Squash mentioned constructive comments, so I'll see if I can toss in something useful. When Nigel pops around the corner, I noticed that he stops somewhat unnaturally. One thing that can help fluidity for slightly rapid movements like that can be one or two ending frames that go in the opposite direction ever so slightly.
A good way to view this in reality is to take your arm, point upward, and move it down in a quick motion. Stop around midway and you'll notice your arm bob slightly up before stopping completely. If you can emulate this in stop motion it can make motion that feels more real.
