Since starting on the Digital / Photo covers for Titan Comics' Doctor Who ranges in 2015, I've been involved in producing covers for a number of special event issues, outside the comics' regular continuity.
These events have included the eight-issue Doctor Who: The Lost Dimension, which ran across a number of Doctors from August - October 2017. For this range, I provided a number of covers for each issue, and a splash design for use on a potential gatefold cover, featuring all the (then) current incarnations of the Doctor.
I was also responsible for the cover on the 2017 Free Comic Book Day issue, which was distributed free from comic shops around the world.
