Not only are the colors and shading superb on this picture, the fact that it's pixelated adds more to the already unique style of the image. The expressions are superbly done, especially Celestia's utilizing a very sharp jaw line to pull out as much intensity in her face as possible. The shading of the image, specifically the hair, adds an extra level of ambiance to the image which draws your attention all throughout the picture rather than focusing solely on the faces.
This is an excellent picture, and the fact that it's gorgeous despite its pixelated nature makes it all the more fantastic.
Chrysalis vs. the World: You must defeat Celestia's 6 "Evil" (more like "meddling") Elements of Harmony (and then the Princess herself, rule of 7) to usurp her throne, date Shining Armor, and realize that day you dreamed since you were small!
