I totally missed Draw a Dinosaur Day. Oh well. Here is my contribution, as appropriate as I could make it for my Viking (etc) blog. [link]
Meant to be a quick sketch, but I kept screwing it up, so it took a while. Oh well. Here it is, for what it's worth. Also, borrowed the word "preenactment" from Dresden Codak.
