Pinkamena and her balloon

Beautiful on that lighting, how it comes from the balloon (which seems like her regular cheerful self) and pulls her depressed form from the dark background.

I first thought she was holding the balloon captive, having tied it to her tail, or maybe she simply forgot it was there until now. When I looked again I realized, maybe that balloon is using what little power it has to try and lift her spirits. it really looks like it's pulling hard to lift her up and illuminating as much as it can. Which really makes me think that it represents her usual perky and Encouraging self.

I think the quote in the comments could easily be coming from the balloon, because pinkie always sees everyone as valuable and worthy of her friendship, no matter how unapproachable they seem, or how little they may think of themselves.
