Why yes, this year was also one filled with illustrations of ponies, so I had to make a separate one with just those ones. October it's perhaps my favorite since it had the most characters I had ever drawn on a single picture.
All of them are exceptionally well drawn and absolutely worth the view. My favorite out of them would be either April or December. Because beautiful Twilight... Maybe December a little more than April for the content. But otherwise they are all great. I hope 2013 will also be a year filled with awesome pony art by you.
