Great and powerful Pinkie sketch

Here's my sketch for next vector, I spent two days for it, first time I sketched Twi and Fluttershy, today I sketched Pinkie and Spike (funny thing never make a vector of him from the show, but that's the second time I drawn him ). Wonder how the finished version will look like, btw I really feel content with the art style, feels closer to show but also more natural for me to draw, guess all that practicing with drawning ponies at free time here and there are slowly paying off
