Drawing wheels on the galaxy note 2

I still can't quite believe it, but I just dumped my iphone in favour of a Samsung Galaxy Note 2.  Yep, made the switcharoo from ios to android.  So far I'm absolutely loving it.  The Note 2 has such an amazing screen and the S-pen is awesome for drawing with.  This weeks illustration friday picture subject was 'Wheel' and this little sketch was done in sketchbook mobile for android on my shiny new phone.
