New Ink + From the Sketchbook

My co-worker gave me a little jar of walnut ink to try out, and today I thought I'd give it a shot. It's awesome! It's like a watercolor and ink in one, and the perfect shade of brown.
Just finished watching the new season of Sherlock and it's incredible. So I doodled John Watson and Sherlock Holmes.

John turned out much better than Sherlock. Surprisingly. Why can't I draw you, Benedict Cumberbatch, with your amazing cheekbones?

And because I have nothing else to share, here's a few doodles from the sketchbook from lately. The pages of blind-contour people are how I keep myself entertainted while waiting for planes to board at the airport.
