Daww, nice song Derpy(and Dinky), Vinyl and Octavia even cried when they heard this, and everypony in the audience is probably crying to the song. They should give each other hugs after the song is done.
Okay, I have to say it here if not anywhere else. You are an incredible artist. Yes, the picture itself is really good, but it's the hidden story and feelings hidden within each that makes your work incredible.
