A random 10th Doctor portrait I started one night to fight the returning art-block.
David Tennant's features are really hard to get down - and I thought Hiddleston!Loki was difficult... *_+;
(I had no idea what I was doing with that shading, btw. 8D; )
An animated gif of some WIP-shots can be found here: [link](Gotta love how the first sketch looks nothing like the final result lol.)
