UPDATED TO VERSION 2 (Fixes a lot of problems, adds new gradients, looks better)
SVG (requires beta Inkscape for best use): [link]
Well this is the first time I've ever vectored something, so I thought I'd give it a shot. Took me almost 11 hours to do.
This is from MLP S3:S1 with Cadance doing her magical fight in her exhaustion and starvation.
The screenshot I got from Cadance sitting on the throne didn't include feet, most of the tail, and bottom of the mane, so I just tried to fill those in the best I could.
Program used was Ponyscape.
's modified Inkscape so you'll need that if you want to use the SVG files with all the AWESOME options.
