DeviantArt member viktoriyarova made a time-lapse video as she recreated a photo from scratch in Photoshop.
It's interesting to see some of the trial and error, and to see her rotate the image at times to work on certain areas. Here's the original photo titled "Evey 2" by DeviantArt member Beethy.
Below is Vicky's final Evey Study illustration:
