I'm tempted to copy and paste what I've said in Tumblr to here but nah. This started out as another humanized ponies fanart(the one at the bottom left) but it somehow evolved into a CD jacket design during the process....it's like magic(or just because I thought it was fun making it into a CD jacket). I guess it's also not helping that I've been listening to a lot of fan remixes lately. O3O
Since this thing doesn't exist(yet) so here's to hoping there will be a MLP OST in the future cause some of the songs in the show are really nice. One can always wish!
Below are the original illustrations for this piece.
EDIT: Just in case, since someone brought it up. I don't mind anyone using this piece as part of a fan tribute(no profit and all), but I would very much appreciate it if I'm credited.
