A couple of friends suggested me to upload this sketch done in Colors 3d, an App which in resume, its like a Basic Paint Tool Sai for mobile devices such as 3DS, Vita and some others (because an inactive artist worths nothing amirite?)
Of course, drawing on a Nintendo 3DS can be slightly difficult mostly due stylus calibration and the considerable lack of space, but it was fun to give it a shot, and Who else but the ever adorable Derpy to be my character of choice for it
Bonus: Colors 3d offers a Timelapse "video" feature where users can see how a sketch was done from the start, for those (somewhat) curious to see how this pic got done, you can take a look here http://colorslive.com/details/1430769
