I drew Dr. Chaotica from Star Trek Voyager from the above YouTube clip. He is an evil villain in a holodeck novel written by the ST character Tom Paris, who plays Captain Proton, Defender of the Earth. The drawing was traced and inked with a Pentel color brush pen on water color paper.
I promise I’ll do an original sketch some day of people in the Star Trek universe. Even so, this technique of tracing and then inking is an excellent way to learn how to ink.
