Not having access to a scanner while I'm larking about the country, I did this piece entirely digitally. The roughs were done in Photoshop, the various elements were inked separately (the Tardis in Photoshop, where I sort of knew what I was doing, and the figures in Manga Studio, where I really didn't but I liked the approximation of an inked brush line better than anything I could ever get out of PS), then I coloured all the bits in Photoshop and assembled them in a configuration to match the rough. I still don't really think I've got Matt Smith down. He's too damn young, that's part of the problem. Give him a few years and he'll have loads of interesting lines to play with, but right now there's nothing to latch on to.
