Twilight Sparkle / Vincent van Gogh
Oh Twi, pony of my soul. I love you forever. Why van Gogh? Well, they are both obsessive, meticulous, quiet, studious, and desperately sought validation (or maybe that's just me). Van Gogh was absolutely fascinating and ridiculously prolific, and to not include him in this series would be a crime. But the most important reason for this mashup is that it makes sense in my head - though it can't be trusted right now because I've been drawing all night, listening to a marathon of MLP:FiM Season 2, and Season 3 premieres in mere minutes.
