– Alastair Adams, president of the Royal Society of Portrait Painters
It's very human - when you look at it, the full face is in front of you, you look straight into the eyes and face.
There are no airs and graces, there's no background context to allude to success or power - it's very much on a level of one to one with the viewer.
It's quite natural, it's open, it's straightforward and very pure - it's immediate and not overly sentimental.
The Duchess of Cambridge has described her first official portrait, which was unveiled today, as "amazing".
