Here is Vectored Windswept Twilight from the Teaser of Season 3.
I tried to get as accurate as possible but there was no high quality video out yet. The Horn was also missing from the video, so I've added it since it would have been awkward having Twilight without a horn.

Edit: Made some Stroke adjustments, Bending of Cutie Mark (was kind of flat) and adjusted the horn slightly.
