Wow, I remember seeing the earlier Alfred stuff years ago. This is pretty fantastic. The mixed media reminds me of Jon Dilworth, and your animation has gotten quite good. I also really enjoyed the King of the Hill allusion in the beginning.
I don't have a ton of things I can think of to critique. There were a few bits that could've used more in-betweens, but I'm sure you're aware of those and it hardly detracts from the piece as a whole. The only thing I could suggest is maybe to work on the color pallette a little. It's by no means bad as it is, but the little people could stand to have fewer colors to make them more readable, and a few filters here and there over the whole shot would probably help it look more focused.
Overall great work, looking forward to seeing more!
