I had to upload this as a PNG instead of an SVG like I prefer because of all the fonts I used. I’ll put an SVG somewhere too eventually tho.
 
Anyway, I really adore the idea of a teenage Flurry Heart being a rebellious teen and the opposite of what you’d expect a girly pink princess pony to be and enjoy, and since there is similar art out there already, I figured I’d put my own spin on things and make her up like I would enjoy, so she’s covered with references and details. The X on her flank is a fake CM that she painted on rather crudely, lest you think I gave her a simple X for a CM.
