Here’s a picture of the sketch I started off with.

Then I traced it in blue, taking liberties with curves and contours along the way. Those eyes are pretty creepy though.

Here’s the final tracing with slightly less creepy eyes.

Then I added stroke and fill colors. But the eyes are still bugging me and the skin color isn’t quite right so…

I adjusted the colors, made the little guy thinner and worked on the eyes and smile a bit.
