I think the biggest hurdle with the YouTube pilot is me. Because we got shot down by two "big" companies I got discouraged at first, but then just super nitpicky about everything I was making. So it's more of a "I need to make something good enough to impress myself" or simply "allow myself to make it regardless" type situation. Right now I just don't really care and I'm so drained from work I barely have time for fun, much less such a big project.
At any rate, here's some examples of the basic frames I did for the animatics. (Fun fact, Odin was in the original pitch, but I can't find a picture of his character at the moment.)
For the 2014 pitch I hand drew everything in pencil, went over the sketches in ink, scanned them in and turned them into simple vectors in Illustrator. Example below:
Here's a screencap of the private forum my friend and I were using to post and discuss everything. It shows our second story, the super villain one.
Example shot from that story's animatic:
Another thing we were doing was making a machinima. Here's a test shot turned into a gif:
