...he is the Doctor!
I started watching "Trial of a Time Lord" yesterday, and I must say, I've taken a real liking to Six. And that coat of his just cried out to be painted. (I did his face, hands, and hair in coloured pencil, as I didn't have any paints that were the right colours.) My reference was this photo.
Now I'm toying with the idea of doing one for every Doctor...
