Vision: One thing is clear: you will always be ok with a good technique and a good shipping. But you got a skillful technique and a perfect shipping, so others have few chance against you. VinylTavia or FlutterDash combined with good technique will always head to a cannonlike, cute impression.
Originality: VinylTavia, despite of it being so impressive, is very common in the MLP fandom. I rated you 3.5/5 for not to ruin up your final grade. But I want to let clear that you got the perfect idea.
Technique: I have no idea what you used here together with your marvelous skills, but it became fabulous. You can see Octavia's hidden deviousness in her eyes and position, you can see the explosive personality of Vinyl in her straight head and wide, brilliant eyes, you can feel Octavia and Vinyl's feelings apart, then together, than apart again. I only rated you 4.5/5 because of one fanart I ever saw that even made me cry. After that, nopony else deserves 5/5...
Impact: I unintentionally described the impact in technique, so you already know why I didn't give you 5/5... Impact and technique are intrinsically linked.
