Well drawn, but the main topic (Jesus vs. Santa) is a very overused joke in the modern pop culture, nothing new here. The end is also a bit of a in-your-face message, even for a selfpromotion.
However, I'm curious about your work (is that an elf warrior on the cover?), maybe next time you make an animation about your book? A short intro about the entire storyline or a significant scene would be something I would like to watch, and I'm sure you would reach a bigger audience with it.
