One thing I noticed in the past season is that we never really got to see the Cutie Mark Crusaders use the abilities of their type of pony; we don't really see Scootaloo fly, we don't see Sweetie Belle do magic, and Applebloom... still not sure what's special about an earth pony other than some vague notion that they have some innate magical bond with the earth? I dunno.
I was looking for an excuse to draw a dangerously adorable humanized Sweetie Belle. She has grown to become my favorite Cutie Mark Crusader so that became pretty much obligatory. Then it dawned to me; why would Rarity try and teach her sister some magic if she can ask the most gifted magician is Ponyville to show her the ropes. Also, it makes for dorky-Twilight, which is always the preferred mode of Twilight.
So here's Sweetie Belle starting out with some basic telekinesis.
I'm also planning to do one with Scootaloo and Applebloom.EDIT
Made some changes to Twilight's face and glasses, and some other minor changes.
Scootaloo: First flight
Applebloom: First repair
