I picked up the pencil again and wanted to doodle Luna’s eye on my lecture notebook, then I started darwing her head and the rest is history. I’ve made the mistake to start on a sheet with my homework still on it, the mistake to experiment with mixing colors on the same sheet and the mistake to use watercolor pencils the wrong way(only having one blue and one purple pencil and try mixing them without using water).
So for the future I will buy some color pencils with more color variety and just draw on my old sketchbook right away.
If the equation is too much of an eyesore for you, just imagine that Luna is thinking about three-dimensional steady-state numerical heat transfer that night, as we all do sometimes. ;)
