Corrupt Data

The hardest part about sketch with pen is realizing that you've screwed up and finishing the drawing anyhow. The answers are in the errors.

Been rewatching one of my favorite shows from my teenage years, Star Trek: The Next Generation. So here's an attempt to draw Data. It was looking like him until I lost control of the shading on the left side. Now it kinda resembles Gary Shandling.

Ah hell, I had to do one more. This time a quickie with the brush pen.
