Great!
I am generally not a person who is for simple moving pictures, but this is an exception! I think this may in fact be the best piece of MLP fanart I've ever seen! Of course, by "best", I mean the kind that comes to the closest to looking like the TV show looks. I love how some of the other pony characters appear in this. This is just what makes the show so awesome with its animation! I do kind of think this should go more in the Art Portal.
I love how you have a really soft melody to soothe the viewer as they are watching this great piece. A full fledged cartoon would be perfect. It's even great to see the drops of water on the ground! It's great to be introduced to someone so talented. This is pretty much everything that made MLPFIM so popular.
