An interesting feature I've found over the last term, which has coincided with Peter Capaldi's first season as The Doctor, is that older pupils (year 5 and upwards) are evenly split between wanting me to draw an older Doctor (mostly Matt Smith, with a small fraction of David Tennant), whereas it's the younger pupils (year 3 and 4) who are devoutly Peter Capaldi fans. Seems you never forget your first Doctor. (Below we can see the flipchart drawings from Kentisbeare in Wiltshire, whose year 4 pupils wanted a Capaldi drawing, and Darley near Harrogate, whose year 6s wanted Matt Smith).
The celebrities they chose to tread on a worm in my demonstration strip were Simon Cowell (twice), Cheryl Cole, Taylor Swift, Bradley from The Vamps, and most imaginative suggestion of the week, Mick Jagger.
