I am really sorry about the edges on this. I had to use a grey background for the screenshots of the vector, and the makes edge-cleaning a heck of a lot harder than white. I would have used white, except there are no borders between the edges of her eyes, and the background.
This is actually from Lesson Zero (Yes, it took me this long to get off my lazy flank and vector it), from when Twilight teleports inside the ball. the only reason I got the screen-cap (150px tall by 75 wide, 320p quality, unholy mess to vector), was because my crappy internet connection makes youtube freeze and buffer in the darndest places.
