"Ringlight" by Catriona E J Lindsay

Another contemplative Doctor Who picture. The Doctor stands on the surface of an uninhabited planet, generally unremarkable but sporting a striking set of rings, which reflect the light of the set sun, like moonlight, but stronger. Has it ever occurred to you that planetary rings would do that? It's a shame that they don't generally form around habitable planets, because I think they'd be a lovely thing to have. Like a huge rainbow.

I did the bulk of the colouring of this while listening to a radio interview with David Tennant. It is strange, and slightly disturbing, to listen to somebody talking away happily about their life, who you have never met, but whose nose you have spent several hours studying in intense detail. I feel like some kind of strange, nasally-fixated stalker.

But the time was well spent. David Tennant has a very surprising nose. Viewed from ahead, it seems like a delicate little nose,  narrow and unobtrusive, but then he turns his head to one side and this enormous beak appears. It has length, but no width. It is, as near as possible, a nose in two dimensions.

Not totally satisfied that I've achieved a likeness, but that's probably a lifelong project. I don't usually draw people, because they are by far the hardest thing to draw, and likenesses are even harder. It doesn't help that I find drawing portraits an unsettling process. It's a little bit like standing very close to someone and staring into their face. For a long, long time. Best to work from photos - at least for practice - although I find even that faintly disturbing.

It's driving me slightly crazy, but it's fun to work on something so challenging.
