If you clicked on the version without background you would have known. This is based on a screenshot (look in my journal for it) which is taken from the official MLP facebook page. So yeah, I'm pretty sure it's canon.
Personally, I liked her old look better. This kind of mane really fits Celestia more than Luna. Also, is it just me or did they darken her colors? Maybe that's just because it's night time in the scene..
Sorry, I meant to type "almost all," that's my bad.
I wasn't trying to offend you, just stating a fact. I'm quite jealous of people who do vectors without tracing though. I've never had a good program to work with vector art, so I've had to stick it out with raster layers.
"All vector art is traced directly from the show"?
I guarantee you that I haven't traced since I was 7ish or so - you look through my gallery, you'll see some my little pony stuff. Since I know most people are too lazy to do that, I'll link it for you. [link] The closest thing you could say I did to 'tracing' here was the "Fresh Prince of Bel Aire" text, because I'm awful at tag-style lettering. Even then, I tweaked it a whole load afterwards.
By the way, the "original" isn't an original EITHER. It's a tracing of the episode teaser on the MLP Facebook page. [link]
