I saw this, and was reminded of the Headless Horse. Which reminded me of the stories in the real world of the Headless Horseman, which reminded me that there are real-world stories of Dullahans. Which got me to thinking... the Headless Horseman was probably based off Dullahans. Which means that the Headless Horse was based off a pony equivalent of Dullahans. which means you've drawn the inspiration for the Headless Horse. Now, while this rant is repetitive and possibly Dull, my point is that this picture was already awesome but thinking about it only made it moreso.
