For those of you not following my Tumblr, I will be uploading one of my Doctor sketches up each day leading up to the Time of the Doctor Christmas Special. Each Doctor caricature takes roughly an hour to draw from sketch to final inking. All 12 were done over the course of 3 days.
Here is the Sixth Doctor played by Baker, no not Tom Baker, Colin Baker. Poor Colin, his Doctor was recently voted the worst. Not his fault, he didn't get the outfit he wanted, or the time to allow his character to evolve. Colin did say he would want to return to DW as a villain, he should as a form of the Valeyard.
You can see all the Doctor pictures on the Regeneration Chart
