Here is a portrait of Arya Stark from the Game of Thrones TV series. Picture referenced from scenes of the show. Adobe Photoshop Touch app for phones on a Samsung Galaxy Note II utilizing the Wacom S Pen. Accumulated 8 hours.
The release of the Photoshop Touch app for phones is roughly 2 weeks. I usually do traditional watercolors and have applied the transparent technique from a white blank to this dramatic dark portrait image. I attribute the accuracy to the Wacom S Pen and portability of the Note II so I was able to do it during free times anywhere, and not be limited by carrying a laptop with a tablet board. Here's a link to the screen shots of my painting process:
