Speedy's Sandwich Bar & Café
One night watching Sherlock with a friend, we started talking about Moriarty's character (played by Andrew Scott), and what he would order in a café. I said it would probably be something extremely sweet; my friend agreed and added that it'd have a flamboyant combination. Taking that as a starting point, I drew a drink with those traits, and followed up with the rest of the characters.
The drawings started out as quick pencil sketches; I then re-drew them in black ink. I digitalized them and applied color to them within a shared palette.
