I caught up with James at the launch, and you can watch a video of the interview above. In it he discusses why he chose to work with a biro rather than a pencil or paints, and how it's not as restrictive a creative tool as you might think. He takes us through the project from conception to creation and tells us how he coped working in a digital form he's not used to on a brand new device.
He also gives us his thoughts on the Surface Pro 3 itself - though as he accepted a commission by Microsoft for the project on the device, it's unlikely he was going to tell us that he hated it.
Read on to see the artworks James created, plus time-lapse videos of how he drew them.
James Mylne's version of the National Portrait Gallery's of William Shakespeare, attributed to John Taylor and the only portrait of the playwright painted from life.
James' take on a portrait of suffragette and author Dame Christabel Pankhurst - daughter of Emmaline.
This piece is based on a not-brilliant portrait of the Brontë sisters - (left-to-right) Anne, Emily and Charlotte - which is notable only for it being the only surviving portrait of the three sisters, and by their brother Patrick Branwell.
