I recently drew a portrait of George Takei that I used for my submission to his logo contest: It's OK to be Takei. This inked portrait was scanned and manipulated in Adobe Illustrator to add text and a curved rainbow, which I was rushed to finish. In hindsight the rainbow could be much smoother and I forgot to include two colors. Oh well, I still like the concept and am happy with the portrait.
