Final piece from yesterdays #urbansketchers #Bielefeld gathering in a café: a quattrochrome (?!) #sketch on mid-tone paper by Stilman & Birn.

Black #fountainPen #inktober9 drawing with diluted ink washes for the shadows, white #gouache for highlights, sepia backdrop, and some blue and pale yellow for the lights in the counter. 4 colors, see?
