The strawpoll said to do this:

Draw 1 OC every day for the month of December. It’s going to work via random selection of those who decide to enter.

Here’s how to enter:

-Go here https://decemberocs.tumblr.com/submit
-Submit a reference of your OC. You can also specify a pose, but it’s alright if you don’t, I’ll come up with something.
-Your submission can be SFW or NSFW
-Your submission can be anthro if you like.
-If your submission doesn’t have a reference of your OC, I will ignore it.

That should be all. I’ll be re-blogging this post every Thursday to make sure people see it.
