I hope that this chalk drawing (chalk along with some charcoal for shades and to mix the darker colors in Twilight's mane) will make up in case the first one offended her Highness ;)
Maybe seeing the two will also encourage some of you to give chalk drawing a try. It is relatively easy to learn, it doesn't take a lot of time and most importantly chalk drawing is a lot of fun, especially when done along with good friends.
