What started to a quick sketch ended up with me pulling out all the stops so I didn't have to stay up to 4:30 in the morning. Roughed with a 2B pencil on Strathmore 9x12 Toned Tan, then inked with Sakura Micron pens, with shading and white highlights with Winsor-Newton Hard, Medium and White Charcoal plus a little 2B and final outlining with a Sakura Pigma brush pen. I like doing renderings on toned paper as you can go up to white and down to dark, giving you more ways to push the drawing. The face still is too wide, and is missing something, compared to the source image (
