This is a beautiful, cute and innocent picture of Pinkie Pie; and the scenery really goes with her.
It is one of the best I've ever seen; and it gives me some inspiration for something to add to an idea I have for an MLP:FiM theatrical film.
By the way though, I’ve noticed that some of the comments say that the clouds are “vomiting” those rainbows, and I see you’ve even confirmed this is one of your previous replies. However, at first glance, it didn’t look like “vomiting” to me; in fact, I would usually never expect such a thing when looking at a cute and innocent image like this (unless of course it we’re something that was on “Adventure Time”, CN, G4, etc; among other exceptions I don't have in mind right now), I actually compare those comments to how people thought “Puff the Magic Dragon” was about smoking Marijuana.; and it does worry me whenever I witness people talk like that on the web (even though I do understand it has become ubiquitous and known for among much of Gen Y throughout the turbulent 2000’s; I just think people should learn to control themselves and say nice things more often than icky things all the time (that would include making up brand new things/words to say); I’m sure you’ll understand that although the Internet should be a place of free speech, that does not make it a ‘potty mouth house of stupidity’).
So it does lead me to wonder (I’m just curious): When you were originally drawing the picture, were the clouds supposed to be “vomiting”? Or, did you only get that idea from the first comment you saw that compared that scene to “vomiting” (and applied it to your own way of looking at your own work)?
