Drew this on my friend's Android phone.

It was hard to control, especially on a teeny 4.3 inch screen (small in artist's standards) And the stylus was the size of my finger; in fact, it was my finger.

Fortunately, autodesk sketchbook mobile has a really convenient pinch zoom, I find it much better than a computer's zoom.

Normally, I won't post something so insignificant, but this looked good.
