I love this artist I just found on the Japanese artists’ site pixiv, Shimizu. I love everything about their style right down to the patina on the sketchbook. You’ll love it too, especially if you are a fan of Top Gear, Doctor Who, Sherlock…I saw at least one great sketch of Tom Hiddleston as well. Check it out–Shimizu’s work can be found here–

I’m not sure how far you can get without creating an account. I did, and it was worth it.
