I wanted to do more pencil sketches of people, but I didn't want to be stuck looking at my computer for the reference photo while I drew. The simplest solution was to use my signed photo of Armin Shimerman as Quark from Star Trek: Deep Space 9. I'm pretty pleased with how this turned out. His shirt was difficult to draw, which is why I only drew a small portion of it. The reference photo I used is here: [link] .
Drawn entirely with HB 0.5mm mechanical pencil, tweaked slightly in photoshop only to optimize the picture after an encounter with the scanner, which always makes things look worse.
