Pinkamena can't stand all these ponies laughing...
LAUGHING AT HER CRIES.
It was dull, rainy day in the train, listening Metallica's Master of Puppets.... And then, the idea of this picture appeared.
[2014 edit] Don't watch me for this creepy Pony stuff. I finished with it, and there will never be more. Thanks. This one is still impressive.
