You don't walk in on Vinyl when she's practicing.
Again, messing around with a different style kind of thing. Vinyl is pretty white, so it's hard to emphasize the stereotypical shininess, and it's hard to work other colors into her coat like I did with Scootaloo. I sort of compensated by doing crazy things with filters and magic.
I tried it with a white background, which makes the shadows more distinct, but the colors and glowy magic stuff show up much better on black. So there you go.
Next up (at some point)- Luna.
