What artists think is impossible to draw: proper anatomy what REALLY is impossible to draw: rarity's hair and twilight's mane. (I've seen a lot of artists on livestream just freak out of which side of her neck it should be on XD) but this is awesome.
I use Quicktime Pro 7 to open a song about the length I want, then copy the video, select the entire song and do edit->add to selection and scale to make it fit the song length. There's probably other ways, but that's worked for me so far.
Nice one. This is quite a bit different than your usual style in that it's pointer and more angular, though I still recognize your distinctive way of drawing the noses. Along with some of the lighting effects you've used (i.e.; more highlights and shine on the hair that your usual work) it gives the picture a much sleeker more polished look, which I think is appropriate to this one since you have Twi floating by the power of her own magic. I particularly like the movement of her bangs here.
