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.
Hey it's humanized Doctor Whooves... actually it's David Tennant! I started watching during the end of Smith's era but going back and watching Tennant, I really like his Doctor much better. McGann is still the best however.
You can see all the Doctor pictures on the Regeneration Chart
