Really cool concept! I have never imagined Twilight Sparkle as Screwball but it's very chaotic vision. You managed to compose the elements of those two - hair, eyes and the look. I think the cutie mark could have been corrupted too.



I like the way it looks - the pony has an interesting pose and the way you made it's appearance is impressive. I like her facial expression too because it goes with the evil and the idea of chaos. Even the background adds dynamic to this work (I see those stains moving!) and some kind of abstractness.



However, I suggest you smudging the lines a bit because on a zoom some of them are very sharp. I don't think it looks fine when you put such a sharp thing on a smooth background.
