My Doctor Who

This is my first submission, so I hope it goes down well. It just struck me one day to draw my own Doctor Who, like it seems to strike many artists to do sooner or later. I'm a big fan of the show, despite having seen less than one one-hundredth of it. Maybe one day it'll start broadcasting in America and I'll find that I hate it. Until then, I'll consider myself an enthusiast. It's the mythology that gets me, see... And in case you're wondering (which I'm sure you are), my favorite Doctor's always been Paul McGann. Hey, they say your first is always your favorite.
So call me old-fashioned, but I've often thought that it'd be nice to see the Doctor return a bit to his old age. I just feel that someone called "doctor" should seem wizened to some degree, and it'd tie him back to his earliest selves. So for this incarnation I made him a bit older than he's been, rather universe-weary and sardonic. But still the good guy. I even made my own little logo down there at the bottom, innit cute?
Say, why isn't there a "fan art" category for Miscellaneous Digital Art around here?

EDIT: I have by this time seen much, much more of the show. And I am still a fan.
